Answer: 128 square centimeters

Explanation:

If the perimeter is 48 cm, then the sum of the lengths of any two adjacent sides must be 24 cm.

Since the length of one of these sides is given to be 8 cm, it follows the length of the corresponding adjacent side is 16 cm.

Thus, using the formula for the area of a rectangle, the area is 128 square centimeters.
