Question

The second side of a triangular deck is 5 feet longer than the shortest side and a third side that is 5 feet shorter than twice the length of the shortest side. if the perimeter of the deck is 64 feet, what are the lengths of the three sides?

Answer 1

let x be the length of the shortest side. second side is 5+x and the last is 2x-5. add these three to get the perimeter 64
x+5+x+2x-5=64
4x=64
x=16
sides are 16, 21, and 27
