The perimeter of the parallelogram is 36cm, and one side of its sides is 2 times larger than the other. find sides

A parallelogram is a quadrangle in which opposite sides are parallel and equal to each other:

AB = CD;

BC = AD.

The perimeter of a parallelogram is the sum of all its sides:

P = AB + BC + CD + AD.

Since the side of the parallelogram BC is twice as large as the side AB, and the perimeter is 36 cm, we express it as follows:

x is the length of the sides AB and CD;

2x – sides ВС and АD;

x + 2x + x + 2x = 36;

6x = 36;

x = 36/6 = 6;

AB = CD = 6 cm;

BC = AD = 2 6 = 12 cm.

Answer: sides AB and CD are 6 cm, sides BC and AD are 12 cm.
