Hi, I need help on this one.

I have two triangles ABC and DEF both are similar. Find the perimeter of triangle DEF.

Triangle ABC: The base is 4CM... the longer side is 3cm...and the small side is 2cm.

Triangle DEF: Is larger than ABC, The base is 16 cm, and one side is
8 cm...the other side is not mention.

How do I find the perimeter of triangle DEF?

Suppose: AB=4
BC=3
AC=2

Therefore: AB/DE = 4/16
BC/EF = 3/12
AC/DF = 2/8

So, DE + EF + DF = 16 + 12 + 8 = 32
