**Reiny**, Wednesday, March 23, 2011 at 10:12pmif the new one is similar to the old one, then it must be

7x by 9x

and its perimeter would be 2(7x+9x) or 32x

so 32x = 260

x = 8.125

so the new one is 7(8.125) by 9(8.125)

or

56.875 by 73.125

check : 73.125/56.875 = 73125/56875 = 2925/2275 = 9/7 --- ratio works

perimeter = 2(56.875) + 2(73.125) = 260 --- checks!
