Hi

It gives the area of the smaller rectangle, let's say it is 40

larger rectangle Area = 160

Ratios of the Areas is the ratio of corresponding sides squared.

 (8/x)^2 = 160/40 = 4

 64/x^2 = 4

 16 = x^2

 4 = x       (Tossing out the negative solution for unit measure)

repeat

(20/y)^2= 4

 20^2/y^2 = 4

400/4 = y^2

 10 = y
