The perimeter of a parallelogram is 88 cm. One side is 3 times larger than the other. find the lengths of the side of the parallelogram.
In order to find the lengths of the sides of a parallelogram, we will compose and solve an equation.
But first, let’s consider the condition of the problem. It says that the perimeter of a parallelogram is 88 cm. It is also known that one side of it is 3 times larger than the other.
We introduce the variable x, denoting the length of the shorter side with it, then the length of the larger side is 3x cm.
We look for the perimeter of the parallelogram by the formula:
P = 2 (a + b);
2 (x + 3x) = 88;
x + 3x = 88: 2;
x (1 + 3) = 44;
4x = 44;
x = 44: 4;
x = 11 cm length of one side and 3 * 11 = 33 cm length of the second.
