| **One side of the parallelogram is 15.4 inches and the other side is 1.4 inches less than the first side, calculate the perimeter of the parallelogram.**

From the condition, we know that one side of the parallelogram has a length of 15.4 dm, and it is also known that the other side is 1.4 dm 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:

15.4 – 1.4 = 14 dm.

We just have to substitute the values and calculate:

P = 2 (14 + 15.4) = 2 * 29.4 = 58.8 dm.
