Answer:
Step-by-step explanation:
let the length of shortest side be x
and length of second side be 2x
and third side be x+17
given , perimeter = 173 feet
therefore , x+2x+x+17 =173
4x =173-17
4x =156
x = 156/4
x = 39
therefore ,
length of :
shortest side = 39 feet
second side =78 feet
third side =56 feet
