12. 15, 27, 36, 17, 25, 32, 49, 111, 121, 13​

Answer 1

Given :-

Diagonal of square = 20 cm.

We know that Area of Square =

1/2 × d²

= 1/2 × 20 × 20

= 10×20

= 200 cm².

Also, area = side²

So,

side = √area

side = √200

Side = 10√2 cm.

Perimeter= 4 × side

= 4 × 10√2

= 40√2 cm.

Hence the perimeter of the square is 40√2 cm.
