A rectangle has a perimeter of 30 inches. One Side measures 5 inches.What are the measurements of the other three sides?

Answer :

Let's say the two on the side are 5 inches, then you're left with 20 inches left. 20/2 sides = 10 inches per side. So the measurements are 5 in, 5 in, 10 in, 10 in.
30 - ( 5 + 5)= 20/2=10
Side A: 5
Side B: 5
Side C:10
Side D:10
