Help!

The problem goes like this:

$In \ \triangle ABC,\ AB=AC=25\ and \ BC=23.\ Points\ D,E,\ and\ F\ are\ on\ sides\ \overline{AB},\ \overline{BC}, \\ and\ \overline{AC},\ respectively, such\ that\ \overline{DE}\ and \ \overline{EF}\ are\ parallel\ to\ \ \overline{AC}\\ and \ \overline{AB},\ respectively.\ What\ is\ the\ perimeter\ of\ parallelogram\ ADEF?$

I don't get what to do, as all I did so far was draw the picture and label.

After that, I'm stuck.

Thank you in advance!

I got the answer! It's 50!

You multiply 25 by 2 to get your answer, right?
