Let width be w. Then length is w+5. So:
w(w+5)=6000
w�+5w-6000=0
(w+80)(w-75)=0
w=75 ft.
w+5=80 ft. ☺☺☺☺

Area = L*W
L = W+5
therefore:
(W+5)*W = 6000
W^2+5W-6000 = 0
(W-75)(W+80) = 0
W-75 = 0 or W+80 = 0
W = 75 or W = -80
Since we're looking for a positive number, let's try 75:
(75+5)*75 = 6000 Correct
