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

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

1. Let’s denote the length of the shorter side of the parallelogram through x cm.

2. Determine the length of the longer side of the parallelogram:

4 * x = 4x cm.

3. Let’s compose and solve the equation:

(4x + x) * 2 = 30;

5x * 2 = 30;

10x = 30;

x = 30: 10;

x = 3.

4. The length of the shorter side of the parallelogram is x = 3 cm.

Answer: the length of the shorter side of the parallelogram is 3 cm.
