Question 711025: A certain building has a rectangular base. The lenght of the base measures 60 ft less than three times its width. The perimeter of the base is 840ft. What are the dimensions of the base?

width = w
length = 3w - 60
2(w) + 2(3w - 60) = 840
2w + 6w - 120 = 840
8w = 960
w = 120
The base is 120 ft wide and 300 ft long.
