The perimeter of a parallelogram is 16 cm, which is equal to its sides of a parallelogram if it is known that one side of it is 3 times larger than the other.

In order to find what the sides of the parallelogram are equal to, we will compose and solve a linear equation.

The condition says that the perimeter of the parallelogram is 16 cm. And we also know that one side of it is 3 times larger than the other.

Let’s start solving the problem by introducing the variable x cm, denoting with its help the length of one of the sides, then the length of the second side can be written as 3x cm.

Let’s create an equation using the formula for finding the perimeter:

P = 2 (a + b);

2 (x + 3x) = 16;

x + 3x = 16: 2;

4x = 8;

x = 8: 4;

x = 2 cm and 2 * 3 = 6 cm of the length of the sides of the parallelogram.
