C 32cm
If you're asking what the length of a side is:
A 8cm
Step-by-step explanation:
Area of a square is calculated by length x width.
And all four sides of a square are equal in length.
Area: 8cm×8cm=64cm2
Perimeter: 8cm + 8cm + 8cm + 8cm= 32cm
Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.
√(64)=8
