**Reiny**, Thursday, July 10, 2014 at 8:46amI would let the width = x

then the length is x+120

and

x(x+120) = 6400

x^2 + 120x - 6400 = 0

which factors to

(x-40)(x+ 160) = 0

x =40 or x = -160, which is not possible, can't have negative width

width is 40, length is 40+120 = 160

check: area = 40(160) = 6400 , yup!!
