**Reiny**, Tuesday, January 29, 2013 at 5:38pmoriginal:

width --- x

length -- x+25

new one:

width --- x-5

length --- x+25-6 = x+19

(x-5)(x+19) = 585

x^2 + 14x - 95 = 585

x^2 + 14x - 680 = 0

(x-20)(x+34) = 0

x = 20 or x is a negative, which would be bogus

original

width is 20 and length is 45
