Similarity of triangles

If triangle ABC ~ to triangle XYZ, AC = 24, AB = 15, BC = 17, and XY = 9, what is the perimeter of triangle XYZ?
Round all sides to 1 decimal place.

Correct answer:

p2 =  33.6

Step-by-step explanation:

AC=24 AB=15 BC=17 XY=9  k=XY/AB=9/15=53=0.6  p1=AC+AB+BC=24+15+17=56  p2=k p1=0.6 56=33.6
