The base and height of an original rectangle are each increased by 15%. The area of the new rectangle is k/w times the area of the original rectangle. If k and w are relatively prime positive integers, find the value of k + w.

A2/A1 = (1.15)^2 = 1.3225 = k/w
If k and w must be integers, and "relatively prime", then
k/w = 13225/10000 must be reduced to the lowest ratio of prime numbers
13225/10000 = 529/400
Are you asking for the value of k+ w, or k AND w? It looks like 529 and 400 are your k and w.
