Area of a square = a x a = 64cm, it means 8 x 8 = 64. So one side of the square is 8 cm. Then perimeter equal to  4 x s. So 4 x 8= 32. So 32 cm is the answer. Hence, option A is the correct answer.

Area = 64
side * side = 64
s^2 =64
s = 8
Perimeter of square = 4 s
=4* 8
= 32 cm

Let, side of square=a

So, a2=64 sq.cm

a=8cm

Perimeter=4a=4×8=32cm.

Perimeter =4a=4×8=32cm

Area of the square = side × side =(side )^2 given area of the square =64 cm^2 now.., 64 = (side)^2 side = √64 side = √8×8 side = 8 ... now perimeter of square..= 4× side = 4× 8 =32 thus , perimeter of the square is 32 cm...

Area of square = side×side
64 sq.cm. = S2
64÷2. = s
32 cm

Area of a square = a x a = 64cm, it means 8 x 8 = 64. So one side of the square is 8 cm. Then perimeter equal to 4 x s. So 4 x 8= 32. So 32 cm is the answer. Hence, option A is the correct answer.
