Please help me with this ACT Prep problem.

Answer:
Option C
Step-by-step explanation:
ΔABC and ΔDEF are similar triangles.
By the property of similar triangles, corresponding sides of the similar triangle are proportional.
[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]
[tex]\frac{6}{DE}=\frac{6}{3}=\frac{10}{5}[/tex]
[tex]\frac{6}{DE}=\frac{6}{3}[/tex]
DE = 3
Perimeter of ΔDEF = Sum of measures of the sides of the triangle
= DE + EF + DF
= 3 + 3 + 5
= 11
Therefore, Option C will be the correct option.
