Sample Problem

The perimeter of the square below is 28 m. What is its area?

Its area is m2.


Perimeter of a square=4× Length of a side ,

Length of a side= Perimeter of a square÷4

Area of a square=Length of a side×Length of a side

So the length of a side  = 28 m ÷ 4 = 7 m

Area of square = 7 m × 7 m= 49 m2

Its area is 49 m2.
