| One side of the rectangle is 8 cm, the adjacent one is 7 cm more, then the second side of the rectangle is: 8 cm + 7 cm = 15 cm. The perimeter of the rectangle is equal to the sum of all its sides. Since the opposite sides of the rectangle are equal, then P = 2 * a + 2 * b, P = 2 * 8 + 2 * 15 = 16 cm + 30 cm = 46 cm. Answer: The perimeter of the rectangle is 46 cm.
