Answer 2

Well

12 feet= 4 yards
6 inches=0.166667 yards
Rectangular portion area=4*0.166667*X yards (X is the unknown width)
Paul needs a total cost of 108.89 and a cubic yard costs $98

So...how many cubic yards can he cover with that? =108.89/98= 1.1111 cubic yards

Hence, 4*0.166667*X=1.1111
X=1.6666 yards which is equal to approximately 5 feet.
