Question

if area of square is 64 cm. Find its perimeter​

Answer 1

Step-by-step explanation:

area=64cm²

let length if side be a cm

so area will be a²

a²=64

a=_/64

a=8cm

perimeter=4a

a=8cm

p=4×8=32cm

Answer 2

Answer:

The formula for the Area of a square is:

A= s×s

Where s is the length of the side of the square.

Substituting and solving for s

gives:

64 units

2=s2

√64units

2=√2s

8 units=s

The formula for the perimeter of a square is:

p = 4s

Substituting the length for the side of the square in the problem we calculated above and solving for

p gives:

p = 4×8 units

p = 32 units

= The perimeter of the square in the problem is 32 units.
