Since the perimeter of a rectangle is the sum of all its sides, we first determine what the sum of the unknown sides is equal to:
32 – 7 – 7 = 18
Accordingly, the second side will be equal to:
18/2 = 9
To get the area of a rectangle, you need to multiply its length and width:
7 * 9 = 63
Answer: 63 cm2
