Question

The perimeter of a triangle is 27 feet. One side is 3 feet longer than the shortest side, and the longest side is twice as long as the shortest side. How long is each side?

Answer 1

Long side: 12

Middle side: 9

Shortest side: 6

Explanation:

Answer 2

6, 9, 12

Explanation:

Let s be the shortest side. Using the information you're given, you can create an equation. 27= s + s+3 + 2s. Now just solve the equation. Subtract 3 from both sides. 24=4s. Divide by 4 on both sides. 6=s. So the shortest side is 6 feet long, so we add 3 to that for the one that is neither the shortest or the longest. That side is 9 feet long. We double s to get 12, which is the longest side.
