The length of rectangle A is 1/3 the length of rectangle B.The width of rectangle A is twice the width of rectangle B.Find the ratio of the area of rectangle A to the area of rectangle B.

Answer 1

If rectangle B has width x and length y, we have

A/B = (x/3 * 2y)/xy = 2/3

just multiply the scale factors: 1/3 * 2 = 2/3
