The width of a rectangle is the length minus 6 units. The area of the rectangle is 27 units. What is the length, in units, of the rectangle?

Answer 1

Area = LW = 27

L=W+6

A= LW = (W+6)W = W^2 + 6W = 27

(W+9)(W-3) =0

W = 3 (ignore the negative solution, sort of)

L=6+W = 9 (looks familiar to that negative solution)

but if you're into alternative or parallel universes, go with -9 and -3

but your instructor may take off points.

Length = 9 Width = 3
