What is the perimeter of a rectangle with the sum of the lengths of adjacent sides equal to 5 cm?

To solve this problem, remember that the perimeter of a rectangle is the sum of the lengths of all its sides. Since in a rectangle the opposite sides are equal, then P = 2 * (a + b), where a is the length, b is the width. Let’s calculate what the perimeter of the rectangle is.

P = 2 * 5 = 10 centimeters.

Answer: 10 centimeters.
