Example 1.
Find the area of a square if the side of the square is 8 cm?

Solution:
Given,
side of the square=8 cm
Area of the square=side Ã— side
=8 Ã— 8=64 sq cm.
Therefore, the area of the square is 64 sq cm.

Example 2.
Find the area of the rectangle of length 13 cm and breadth 8 cm?

Solution:
Given,
The length of the rectangle=13 cm
The breadth of the rectangle=8 cm
Area of the rectangle=Length Ã— breadth
=13 Ã— 8=104 sq cm
Hence, the area of the rectangle is 104 sq cm.

Example 3.
Find the area of the rectangular room of length whose length is 180 m and breadth is 50 m?

Solution:
Given,
The length of the rectangular room=180 m
The breadth of the rectangular room=50 m
Area of the rectangular room=length Ã— breadth
=180 Ã— 50
=9000 sq m
Therefore, the area of the rectangular room is 9000 sq m.

Example 4.
The area of the square field is 121 sq cm. Find the side of the square field?

Solution:
Given,
The area of the square field is=121 sq cm
Area of the square=s Ã— s=s2
121=s2
s2=121
s=$$\sqrt{121}$$
s=11
Hence, the side of the square is 11 sq cm.

Example 5.
The cost of cementing a square yard at Rs 3 per sq meter is 1200. Find the money needed for fencing it at a rate of Rs 6 per meter?
Solution:
Given,
The cost of cementing a square yard at Rs 3 per sq meter is= 1200
Let the side be X m.
Rate of cementing=Rs 3 per sq m
Total cost=1200
Area for cementing=1200/3=400
x2=Â 400
x=20
The perimeter of the yard=4a
=4(20)
=80 m
Rate of fencing=Rs 6 per meter
The total cost of fencing the square yard is 80 Ã— 6=Rs 480
Therefore, the total money needed for fencing the square yard is Rs 480.

Example 6.
The perimeter of a square is 120 m. Find the area of the square?

Solution:
The perimeter of a square=120 m
4a=120
a=120/4
=30 sq m
Therefore, the area of the square is 30 sq m.

Example 7.
Find the length of the rectangular garden whose area is 450 sq cm and breadth is 50 cm?

Solution:
Area of the rectangular garden=450 sq cm
The breadth of the rectangular garden=50 cm
The length of the rectangular garden=450/50
=9 cm
Therefore, the length of the rectangular garden is 9 cm.

Example 8.
A square with a side of 6 cm and a rectangle with a width of 3 cm has the same area. what’s the length of the rectangle?
Solution:
area of the square=62
=36 sq cm
The width of the rectangle=3 cm
l Ã—3=36 sq cm
l=36/3=12 sq cm
Hence, the length of the rectangle is 12 sq cm.

Example 9.
A square with a side of 5 cm and a rectangle with a width of 5 cm has the same area.Â  What is the length of the rectangle?
Solution:
The area of the square is=52=25
The width of the rectangle=5 cm
l Ã—5=25
l=25/5=5
Hence, the length of the rectangle is 5 cm.

Example 10.
Find the cost of painting a square board of side 49 cm at the rate of Rs 5 per sq cm?

Solution:
Given
side of a square=49 cm
Area of the square=side Ã— side=(49)2
=2401 sq cm
The cost of painting the square board at a rate of Rs 5 per sq cm is
2401 Ã— 5=Rs12005
Therefore, the cost of painting the square board is Rs. 12005.
