Question

The second side of a triangular deck is 4 feet longer than the shortest​ side, and the third side is 4 feet shorter than twice the length of the shortest side. If the perimeter of the deck is 60 ​feet, what are the lengths of the three​ sides?

Answer 1

15,19,26

Explanation:

second side of a triangular deck is 4 feet longer than the shortest​ side,

shortest​ side = x

second side = x+4

third side = 2x-4

perimeter = 60 = x+x+4+2x-4 =4x

x=15

second side = x+4 =19

third side = 2x-4 =30-4 =26
