Answer:
63 feet long and 10.5 feet wide
Step-by-step explanation:
147 is the maximum amount of fencing, which means that this is dealing with perimeter.
So we set up our equation:
6x + 6x + x + x ≤ 147
(x being the width, and 6x being the length, which is 6 times the width)
this simplifies to:
14x ≤ 147
simplify:
x ≤ 10.5
So the width of the fencing is 10.5 feet long, meaning that the length is 63 feet long.
Check answers:
6(10.5) + 6(10.5) + 10.5 + 10.5 = 147
63 + 63 + 21 = 147
126 + 21 = 147
147 = 147
It works, so that is the solution.
Hope this helped :)
