Solve the problem.

krok68 [10]

Answer:

Step-by-step explanation:

Perimeter = 84 feet

Side One = Side Two + 12 feet

Side Two + 17 = Side Three

Side Two + Side Two = Side Four

Perimeter = (Side Two + 12) + (Side Two) + (Side Two + 17) + (Side Two + Side Two) = 5 x (Side Two) + 29 = 84

5x + 29 = 84

5x = 55

x = 11

Side Two = 11 feet

Side One = 11 + 12 = 23 feet

Side Three = 11 + 17 = 28 feet

Side Four = 11 X 2 = 22 feet
