Find the perimeter of the rectangle if its length is 8 cm and its width is 2 times less.

To solve this problem, remember that the perimeter of a rectangle is the sum of the lengths of all its sides. Since the opposite sides in a rectangle are equal, then P = 2 * (a + b), where a is the length, b is the width. We calculate what the width is, knowing that it is 2 times less than the length.
b = 8/2 = 4 centimeters.
Let’s calculate what the perimeter is.
P = 2 * (4 + 8) = 2 * 12 = 24 centimeters.
Answer: 24 centimeters.
