Question

A square is of area 64 cm. What is its perimeter?​

Answer 1

32 as the side=8 which can be found from area given

Answer 2

$area = {length}^{2}$

$64 = {length}^{2}$

Taking square root on both sides

$8 cm= length$

So Perimeter will be

$perimeter = 4 \times length$

$perimter = 4 \times 8 = 32cm$
