Given that Jason has 144 feet of material and all is used in building fence.
It means that perimeter of fence is 144 feet.
2. Width of fence = 9 feet
let the length be x
perimeter of rectangle = 2( length + width)
then perimeter of fence will be = 2(9+x)
As given above perimeter of fence is 144 feet.
2(9+x) = 144
=> 9 + x = 144/2 = 72
=> x = 72 - 9 = 63
Length = 63 feet.
