Question

Find the area of square park whose perimeter is 80m

Answer 1

Perimeter of square=4×side

so 4×side=80m

side=80/4

so, side=20m

now area of square=side × side

so,

20m×20m=400m^2

area of square =

400m^2...

Answer 2

perimeter =4*Side
4s=80
s=80/4=20

side =20
area of Square =side²
20*²=20*20
=400m²
