| The condition says that one side of the parallelogram has a length of 13.4 cm, and it is also known that the other side is 0.8 cm less.
In order to find the perimeter of a parallelogram, we will first of all recall the formula for finding the perimeter of a parallelogram:
P = 2 (a + b), where a and b are the lengths of the sides of the parallelogram.
We know the length of one of the sides, let’s calculate the length of the second side:
13.4 – 0.8 = 12.6 cm.
We just have to substitute the values and calculate:
P = 2 (13.4 + 12.6) = 2 * 26 = 52 cm perimeter of the parallelogram.
