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.
