1. 1. Find the perimeter.

2. 1. Answer Start out by labeling all of the parallel sides.

3. 1. Answer continued As we can see the sum of the small orange vertical sides is equal to the large orange vertical side. The same applies with the teal horizontal sides as well. x + 1 + 2 = 7 5 + y + 3 = 10 x y

4. 1. Answer continued Now solve for the missing sides: x + 1 + 2 = 7 x + 3 = 7 x = 4 5 + y + 3 = 10 y + 8 = 10 y = 2

5. 1. Answer continued To finish up the problem, just add up all of the sides and you will have the perimeter! 7 + 10 + 4 + 3 + 1 + 2 + 2 + 5 = 34

6. 2. Find the perimeter.

7. 2. Answer Start by breaking down the shape into smaller shapes.

8. 2. Answer continued. Now use parallel sides to find the legs of the right triangle. x + 8 = 11 x = 3 5 + y = 9 y = 4

9. 2. Answer continued Now use Pythagorean theorem to find the hypotenuse of the right triangle. 3 2 + 4 2 = z 2 25 = z 2 5 = z

10. 2. Answer continued Now find the perimeter by adding up all of the outside edges. 8 + 5 + 5 + 11 + 9 = 38
