Question

the perimeter of a square in 20 cm find its area

Answer 1

Perimeter = 4 × side
20/4 = length of side
Length of side is 5cm
Area is side ^2
5×5 = 25cm^2

Answer 2

Hi friend,

Here is your answer,
_____________________________________________________________

Side = 20 cm

Perimeter = 4*(Side)
                = 4*20
                = 80 cm

Area = (Side)²
         = (20)²
         = 400 cm²
