8. The perimeter of AEFG is 32.

Step-by-step explanation:

First, we need to find what four numbers ADD up to 32.

So, we divide 32 by 4 which is 8.

Then, we add 8 plus 8 plus 8 plus 8 and that equals 32.

                                      OR

20 plus 10 plus 1 plus 1 which also equals 32 as perimeter.

Hopes this helps~~~ :)
