Final answer:
To find the perimeter of a square with a given area, you can find the length of one side by taking the square root of the area. Then, multiply the length of one side by 4 to find the perimeter.
Step-by-step explanation:
To find the perimeter of a square, we need to know the length of one side. In this case, the area of the square is given as 64m². The formula for the area of a square is side length squared, so we can find the length of one side by taking the square root of the area: √64 = 8m. The perimeter of a square is 4 times the length of one side, so the perimeter of this square is 4 × 8m = 32m.
