To find

The area of square = ?

Solution

We know that

perimeter of square = 4 × side

20 = 4 × side

side = 20/4

side = 5 cm

Area of square = side^2

= 5^2

= 25 cm^2

so the area of square is 25cm^2

Answer 2

Perimeter = 4 × side = 20 cm

Therefore, side =20 cm / 4
=5 cm

Now, Area = side × side

= 5 × 5 cm ^2

=25 cm^2
