The side of the rectangle is 8 cm, the other is 4 times shorter. Find the area and perimeter of this rectangle.

Since one side of the rectangle is eight centimeters, and the second is 4 times shorter, to find out the value of the second side, you need to divide the value of the first side by the number 4: 8 cm: 4 = 2 cm – the second side of the rectangle. The perimeter of a 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. Therefore: P = 2 * 8 cm + 2 * 2 cm = 16 cm + 4 cm = 20 cm.The area of the rectangle is equal to the product of length and width: S = a * b, S = 8 cm * 2 cm = 16 cm square.
