Step-by-step explanation:
Answer:
42 ft, 60 ft, 84 ft
Step-by-step explanation:
let x be the shortest side , then the other 2 sides are 2x and x + 18, so
x + 2x + x + 18 = 186 , that is
4x + 18 = 186 ( subtract 18 from both sides )
4x = 168 ( divide both sides by 4 )
x = 42
Then lengths of sides are
x = 42 ft
2x = 2 × 42 = 84 ft
x + 18 = 42 + 18 = 60 ft
