One side of the rectangle is 14 cm. Find the lengths of the other three sides of the rectangle if its perimeter is 64 cm.

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. Let one side be x knowing. that the two sides are equal to 14 centimeters, the perimeter is equal to 64 centimeters, we will draw up an equation.
2 * (x + 14) = 64;
x + 14 = 64/2;
x + 14 = 32;
x = 32 – 14;
x = 18 centimeters.
Answer: 18 cm, 18 cm, 14 cm.
