Area Questions with Solutions

1. Find the area of a circle if its diameter is 42 cm. (Use π = 22/7 )

Given: Diameter, d = 42 cm.

Hence, Radius, r = d/2 = 42/2 = 21 cm

We know that the area of a circle = πr 2 square units.

A = (22/7) × 21 × 21

A = 22 × 3 × 21

A = 1386 cm 2 .

Therefore, the area of the circle = 1386 cm 2 .

2. Calculate the radius of a circle if its area is 25π m 2 .

Given: Area = 25π m 2

We know that area of a circle = πr 2

Hence, we can write,

Hence, r = 5 m

Therefore, the radius of the circle is 5 m.

3. Find the area of a square whose side length is 7 cm.

Given, Side, a = 7 cm.

As we know, the area of square = a 2 square units

A = 7 2 cm 2

A = 49 cm 2

Hence, the area of the square is 49 cm 2 .

4. Compute the side length of a square, if its area is 121 cm 2 .

Given: Area of a square = 121 cm 2 .

We know that, A = side 2 square units

121 = side 2

Side = 11 cm

Therefore, the side length of the square is 11 cm, if its area is 121 cm 2 .

5. Determine the area of a rectangle, if its length is 11 cm and breadth is 9 cm.

Given: Length = 11 cm

Breadth = 9 cm.

We know that the formula to find the area of a rectangle is:

Area = Length × Breadth square units

Area = 11 × 9 cm 2

Area = 99 cm 2

Therefore, the area of the rectangle is 99 cm 2 .

6. Compute the breadth of a rectangle if its area is 84m 2 and length is 12 m.

Area of a rectangle = 84 m 2

Length = 12 m

As we know,

Rectangle’s area = Length × Breadth

84 = 12 × Breadth

Therefore, Breadth = 84/12

Breadth = 7 m.

Hence, the breadth of the rectangle is 7 m if its area is 84 m 2 and length is 12 m.

7. Find the area of a parallelogram, if its base length is 9 cm and height is 5 cm.

Given: Base length = 9 cm

Height = 5 cm.

The formula to calculate the area of a parallelogram is:

Area = Base × Height square units.

On substituting the given values, we get

Area = 9 × 5 cm 2

Area = 45 cm 2

Therefore, the area of the parallelogram is 45 cm 2 .

8. Compute the area of a triangle, if its base measurement is 6 cm and height is 10 cm.

Given: Base, b = 6 cm

Height, h = 10 cm.

We know that the area of a triangle = (½) × b × h square units.

Now, substitute the given values, we get

A = ½ × 6 × 10 cm 2

A = 3 × 10 cm 2

A = 30 cm 2

Therefore, the area of the triangle is 30 cm 2 .

9. Determine the height of a triangle, if its base length is 8 cm and its area is 52 cm 2 .

Given: Base length, b = 8 cm

Area = 52 cm 2

As we know, the area of a triangle is ½ bh square units

52 = (½) × 8 × h

52 × 2 = 8 × h

104 = 8 × h

Hence, the height of the triangle is 13 cm if its base is 8 cm and its area is 52 cm 2 .

10. Determine the area of a rhombus if its diagonals are 7 cm and 10 cm.

Diagonal 1 = 7 cm

Diagonal 2 = 10 cm

The area of a rhombus = ½ × diagonal 1 × diagonal 2

Now, substitute the values, we get;

Area = ½ × 7 × 10 cm 2

Area = 7 × 5 cm 2

Area = 35 cm 2

Therefore, the area of the rhombus is 35 cm 2 , if its diagonals are 7 cm and 10 cm.

REAL WORLD PROBLEMS INVOLVING AREA AND PERIMETER

Problem 1 :

The diagram shows the shape and  dimensions of Teresa’s rose garden.

(a) Find the area of the garden.

(b) Teresa wants to buy mulch for her garden. One bag of mulch covers  12 square feet. How many bags will she need?

area problem solving questions

By drawing a horizontal line, we can divide the given shape into two parts as shown below.

area problem solving questions

(1) ABCD is a rectangle

(2) CEFG is also a rectangle

Area of the garden

= Area of rectangle ABCD + Area of the rectangle CEFG

Area of rectangle ABCD :

length AB = 15 ft and width BD = 9 ft

= length x width 

 =  15 x 9

=  135 ft ²  ----(1)

Area of rectangle CEFG :

length CE = 24 ft and width CF = AF - AC ==> 18 - 9 = 9 ft

 =  24 x 9

=  216 ft ²  ----(1)

(1) + (2) 

Area of the rose garden = 135 + 216 ==> 351 ft ²

Number of bags that she needed = 351/12 ==> 29.25

So, she will need 30 bags of mulch

Problem 2 :

The length of a rectangle is 4 less than 3 times its width. If its length is 11 cm, then find the perimeter. 

Let w be the width of the rectangle.

Then, its length is (3w - 4).

Given : Length is 11 cm. 

Then, 

Length (l)  =  11

3w - 4  =  11

3w  =  15

w  =  5

So, the perimeter of the rectangle is 

=  2(l + w)

=  2(11 + 5)

=  2(16)

=  32 cm

Problem 3 :

The diagram shows the floor plan of a hotel  lobby. Carpet costs $3 per square foot. How  much will it cost to carpet the lobby?

area problem solving questions

By observing the above picture, we can find two trapeziums of same size. Since both are having same size. We can find area of one trapezium and multiply the area by 2.

Area of trapezium = (1/2) h (a +  b)

h = 15.5 ft  a = 30 ft  and b = 42 ft

  =  (1/2) x 15.5 x (30 + 42)

  =  (1/2) x 15.5 x 72 ==> 15.5 x 36==> 558 square feet

Area of floor of a hotel  lobby = 2 x 558

 =  1116 square feet

Cost of carper per square feet = $3

=  3 x 1116 ==> $ 3348

Amount spent for carpet =    $ 3348.

Problem 4 :

The cost of fencing a circle shaped garden is $20 per foot. If the radius of the garden is 14 feet, find the total cost of fencing the garden. ( π  =  22/7).  

To know the length of fencing required, find the circumference of the circle shaped garden.

Circumference of the circle shaped garden is 

=  2πr

Substitute 22/7 for π and 14 for r. 

=  2(22/7)(14)

=  88 feet

Total cost of fencing is 

=  88(20)

=  $1760

Problem 5 :

Jess is painting a giant arrow on a playground. Find the area of  the giant arrow. If one can of paint covers 100 square feet,  how many cans should Jess buy?

area problem solving questions

Now we are going to divide this into three shapes. Two triangles and one rectangle.

area problem solving questions

Area of rectangle = length x width

   =  18 x 10 ==> 180 square feet

Area of one triangle = (1/2) x b x h

   =  (1/2) x 6 x 10 ==> 30 square feet

Area of two triangles = 2 x 30 = 60 square feet

Total area of the given shape = 180 + 60

=   240 square feet

one can of paint covers 100 square feet

Number of cans needed = 240/100 = 2.4 approximately 3.

So, Jessy has to 3 cans of paint.

Length and Area Problem Solving

To solve problems on this page, you should be familiar with the following: Perimeter Area of Triangle Area of Rectangles Area of Circles

You should also know the following formulas:

  • Square with side length \(L\): Area is \(L^2\), and perimeter is \(4L \).
  • Rectangle with side length \(L\) and breadth \(B\): Area is \(L\times B\), and perimeter is \(2(L+B) \).
  • Equilateral triangle with side length \(s\): Area is \( \frac {\sqrt3}4 s^2 \), and perimeter is \(3s\).
If the area of a square is 144, what is the perimeter of the square? ANSWER Let \(L\) denote the area of the square, then \(L^2 = 144 = 12^2 \) or \(L =12\). Note that we are only taking the positive root because \(L\) represents a physical dimension. Thus the perimeter of the square is \(4L = 4\times 12= 48. \ _\square\)
The ancients talked about "squaring the circle," by creating a square and a circle which have the same area. If the radius of the circle is 1, what would be the side length of the square? ANSWER Let the side length of the square be \( S \). Then, we are given that \( S^2 = \pi \times 1 ^2 = \pi \). Taking square roots, we obtain \( S = \sqrt{\pi } \). \(_\square\)
If the ratio of the area of a square to the area of an equilateral triangle is \( 4 : 3 \), what is the ratio of the side length of the square to the side length of the equilateral triangle? Let the side length of the square be \(S\). Then the area of the square is \(S^2 \). Let the side length of the equilateral triangle be \(T \). Then the area of the equilaterial triangle is \( \frac{ \sqrt{3}} {4} T^2 \). We are given that \( \frac{ S^2 } { \frac{ \sqrt{3}} {4} T^2 } = \frac{4}{3} \), or that \( \frac{ S^2 }{ T^2 } = \frac{ \sqrt3 } { 3 } \). Taking square roots on both sides, \( \frac{ S } { T} = \frac1{3^{1/4}} \). \(_\square\)
If a square and a circle have the same perimeter, which of them will have a greater area? ANSWER Let the radius of the circle be \(r\) and the side length of the square be \(s\). Then \[2\pi r=4s \Rightarrow r=\dfrac{2s}{\pi}.\] Now the area of the square is \(s^2,\) and the area of the circle is \(\pi r^2 = \pi \times \left(\dfrac{2s}{\pi}\right)^2=\dfrac{4s^2}{\pi}.\) Then the ratio of the area of the square to the area of the circle is \(\dfrac{s^2}{\hspace{2mm} \frac{4s^2}{\pi}\hspace{2mm} } = \dfrac{\pi}{4} <1.\) Hence, the circle has a larger area. \(_\square\)

Line segments are drawn from the vertices of the large square to the midpoints of the opposite sides to form a smaller, white square.

If each red or blue line-segment measures \(10\) m long, what is the area of the smaller, white square in m\(^{2}?\)

A triangle, a square, a pentagon, a hexagon, an octagon, and a circle all have the same perimeter.

Which one has the smallest area?

Note: All of the polygons are regular.

Four squares of respective side lengths 4, 9,15, and 21 are arranged as shown. Find the length of the yellow line. If your answer can be expressed as \(\frac{a}{7}+\frac{b}{7}\sqrt{c}\), where \(c\) is square free, give \(a+b+c.\)

Note: Neglect the thickness of the lines.
