Answer:
Area = 64 cm² ; Perimeter = 32 cm
Explanation:
Since we know that the side lengths of a square are all equal, this means that all 4 square lengths are 8 cm. Knowing that, we could simply square one of the side lengths to find the area:
8² = 64 cm²
To find the perimeter, just add all the side lengths. There are four sides to a square so we can just multiply the side length by 4:
8 · 4 = 32 cm
