# One of the sides of the parallelogram is 4 times larger than the other. P = 40cm. What are the sides of a parallelogram?

In order to find the sides of a parallelogram, we will compose and solve an equation. Let’s start by analyzing the problem statement.

It is known from the condition that the perimeter of the parallelogram is 40 cm, and it is also known that one of the sides is 4 times larger than the other.

We introduce the variable x, denoting the length of one of the sides with it, then the length of the second side is 4x cm.

P = 2 (a + b);

We compose and solve the equation:

2 (x + 4x) = 40;

x (1 + 4) = 40: 2;

5x = 20;

x = 20: 5;

x = 4 cm one of the sides, then 4 * 4 = 16 cm the length of the second side.
