Answer:

Step-by-step explanation:

So a square is equal on all sides if I'm correct so. The area is pretty much the length x width. So 8 times 8 equals 64.

Hope this helps, have a good day

s = 8cm (Answer A)

Step-by-step explanation:

The area of a square, A, is the square of the length of any one side:

A = s².

If A = 64 cm², then 64 cm² = s².

Taking the square root of both sides yields s = 8cm (Answer A)
