**jai**, Thursday, October 28, 2010 at 12:51amfirst represent unknowns with variables:

let x = length of the second carpet

let x+30 = length of first carpet.

since Area=length*width, and they have the same area,

Area = 9*(x+30) = 15*x

9(x+30) = 15x

now solve for x. then substitute this to x+30 to get length of first carpet.

let me see your work. :)
