# One side of the parallelogram is 15.4 inches and the other side is 1.4 inches less than

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.
