Dr. Bhatia mixes 2 liters of a 5% saline solution with x liters of a 9% saline solution. The table shows the amount of each solution used. A table titled Saline Solution, showing Amount in liters, Concentration, and Total. The first row shows, 5 percent Saline, with 2, 0.05, and 0.1. The second row shows 9 percent Saline, with x, 0.09, and 0.09 x. The third row shows, Mixture, with 2 plus x, 0.08, and 0.64.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
