## Steps to find the perimeter

1. Find all of the missing sides of the irregular shape by either:

- comparing parallel sides

- breaking the shape down into smaller shapes

2. Find the sum of all of the outside edges.

## Perimeter Practice

Step-by-step examples of how to find the perimeter of irregular shapes.

## Steps to find the area

1. Break down the irregular shapes into smaller shapes.

2. Find the edges of the smaller shapes.

3. Calculate the area of each small shape.

4. Add all of the areas of the small shapes (the sum will be the area of the irregular shape).

Sam, Using the Alveolar Air Equation Calculate the PA02 on an Fio2 of 50% and the Aa gradient with a Pa02 of 80. Just simple math. Oh, the pB is 747 and the atm.H20 tension is 44. Still feel like a bright boy?
