One side of a parallelogram is 4 times larger than the other. Find the length of the shorter side

One side of a parallelogram is 4 times larger than the other. Find the length of the shorter side if the perimeter of the parallelogram is 30 cm.

Since the perimeter is known, we can solve the problem by writing an equation.

1. The size of the length is one x centimeters.

2. Length of the other x * 4 = 4x centimeters.

3. Let’s compose the equation.

(x + 4x) * 2 = 30;

10x = 30;

x = 30/10 = 3;

x = 3;

Answer: x = 3 centimeters – this is one side, the second x * 4 = 3 * 4 = 12 centimeters.
