first 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. :)
