##### Objective:

This packet covers how to find the area and perimeter of irregular shapes.

(more)

## 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).

break the shape into rectangles and then find the area for each rectangle. (length x width) then add all area's together. Don't forget to label with squared.

find all of the units of the shape and add them up

tip to remember what to do for area or perimiter:
when you see perimiter remember that you add all the sides a a way to remember that is there is a "T" in the word perimiter and it looks like a addition sign

Triangles are similar to rectangles for finding the area. You still multiply length times width but since it takes 2 triangles to make a rectangle divide the area by 2. This will give you the area of a triangle

"Examples of area are essential here. Also some examples with circles or parts of circles would be good."
