The two triangles below are similar. What
is the perimeter of triangle XYZ?

Since they are similar, we can just take the proportions and apply it to each side :)

 

15/6 = 2.5, which means each side of the triangle LMN are 2.5 times longer than that of the other triangle.

 

20 ÷ 2.5 = 8

25 ÷ 2.5 = 10

 

This means the perimeter of triangle XYZ = 6 + 8 + 10, which gives 24cm, which is your answer :)

 

Hope this helps
