1. The area of a rectangle is the product of its length and width. The perimeter of a rectangle is the sum of the lengths of all its sides. This means that to find the area and perimeter of a rectangle, you need to know its length and width.

2. The length of this rectangle is 15 cm, and the width is 8 cm less, which means that the width is 15 – 8 = 7 cm.

3. Then the area of the rectangle is 15 * 7 = 105 cm2, and the perimeter of the rectangle is 15 + 7 + 15 + 7 = 2 * (15 + 7) = 2 * 22 = 44 cm.

Answer: the area of the rectangle is 105 cm2, the perimeter of the rectangle is 44 cm.
