1. The perimeter of a rectangle is the sum of the lengths of all its sides, or twice the sum of its length and width. We know the length of one side of the rectangle, so to calculate its perimeter, we need to find the length of the second side of the rectangle.

2. The area of a rectangle is the product of its length and width. Knowing the area and one of the sides of the rectangle, you can find the other side as a quotient from dividing its area by the length of the known side.

3. Therefore, the length of the second side is 32/8 = 4 cm. Then the perimeter of the rectangle is: 2 * (8 + 4) = 2 * 12 = 24 cm.

Answer: The perimeter of the rectangle is 24 cm.
