The first thing we must do for this case is to look for the area of each rectangle. We have then: A1 = (40) * (x) A2 = (1.25 * 40) * (y) Then, we have the following relationship between areas: "the area of Q is 10% less than the area of p" A2 = 0.9 * A1 Substituting values we have: (1.25 * 40) * (y) = 0.9 * ((40) * (x)) We rewrite: 50y = 36x The relationship x: y is: x / y = (50) / (36) Simplifying: x / y = (25) / (18) Answer: the ratio of x:y is: 25:18
