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
