The perimeter of a parallelogram is 80 inches, and the length of 1 side is 15 inches. If it can be
determined what are the lengths, in inches, of the other 3 sides?

Step-by-step explanation:

First, draw a parallelogram and label the sides with the dimensions L, S=9, L, and S=9. [note: opposite sides of a parallelogram are of equal lengths]

The problem statement tells us the value of P [the distance around] = perimeter = 48 = L + 9 + L + 9.

48 = 2L + 18

30 = 2L [subtract 18 from both sides]

15 = L [divide both sides by 2]

Check: If L=15 and S=9, what is P?

P = 15 + 9 + 15 + 9

P = 48 [that checks!]
