Finding the Area of Irregular Shapes

Finding the area of an irregular shape can be difficult. It takes some logical thinking, especially when missing sides are thrown in! We began by figuring out the missing dimensions. We used the opposite sides to help us with this. Once we did this, we had to find regular shapes (squares and rectangles) within the irregular shape. Once we found the area of those, we could add them together to get the area of the whole shape. Hopefully the pictures help explain our process. This is definitely more difficult than finding the area of regular shapes!
