Hey! Let me help you on this one.
In order for us to solve this problem, let's break it apart first.
![ABD](https://img.qammunity.org/2019/formulas/mathematics/high-school/7qppr32p9wy0adv2j1r1slua8rn5dg9sdz.png)
is congruent to
![CBD](https://img.qammunity.org/2019/formulas/mathematics/college/4k1hrim8l8f6jap0l2ux1o4yv63n7wf1cg.png)
, or in other words, they are the same.
As it stated, perimeter of
![ABD](https://img.qammunity.org/2019/formulas/mathematics/high-school/7qppr32p9wy0adv2j1r1slua8rn5dg9sdz.png)
is 12 feet, and just like we mentioned before, both of these figures are perfectly congruent.
This means that both of these figures have the same perimeter as well!
Answer: The perimeter of CBD is 12 feet.
