Step-by-step explanation:

22.5 cm

Step-by-step explanation:

You can make a proportion of the sides of the two triangles: AB/FG = 9/13.5 = 1/1.5 = 2/3

You also can do the same thing with another set of two sides: AC/FH = 12/18 = 2/3.

Then, you know the proportion is 2/3 so you have BC/GH = 2/3 = 15/x

Solving:

multiply both sides by 3x
