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.
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).
so what this is saying is you have to turn the 4 and 3 part into 12, and then the 12 into 4 and do 4 and 2, and then you have to do 4 and 4?
Just break theshape into two rectangles and then find the area of the rectangles
