Finding the Perimeter and Area of Composite Figures 
Finding the Area of Composite Figures
Students are to create a composite figure and then calculate the perimeter and area of each shape and then the total for that figure. Student Friendly Learning Objective: I will decompose figures formed by quadrilaterals, triangles, and circles into non-overlapping rectangles to determine the perimeter and area of the figure.
