The assessment for this lesson is to participate in a discussion about composite figures. You will be able to participate in the discussion throughout the unit.
You are required to complete the following:
1) Respond to the discussion topic.
2) Respond to your two of your classmates’ ideas as well.
Discussion Topic: What is an example of a composite figure in your home or community? How would you decompose it to find the area? Can you think of another reason that it would be helpful to decompose these figures in addition to making it easier to find the area of the figure?
It needs to be at least two diffrent shapes

An example of a composite figure in my home is a rug. The rug is composed of two shapes, a rectangle and a circle. To find the area of the rug, I would decompose it into the two shapes and calculate the area of each shape separately. Another reason it would be helpful to decompose these figures is to find the perimeter. By decomposing the figure into its individual shapes, it is easier to calculate the perimeter of the figure by adding up the perimeters of the individual shapes.
