**Reiny**, Friday, October 9, 2009 at 8:42amLet the length of the shorter rug be l feet

then the length of the longer rug is l+30 feet

Doesn't it say that

area of shorter = area of longer ?

15l = 9(l+30)

15l = 9l + 270

6l = 270

l = 45

so the two rugs are 15 by 45 adn 9 by 75

check: 15x45 = 675

9x75 = 675
