The document provides examples of calculating the area of composite figures, which are shapes made up of more than one basic geometric figure. It shows how to find the total area of Melissa's room by breaking it into two parallelograms. It also shows calculating the area of Georgia's garden by finding the area of a rectangle and triangle. Finally, it demonstrates computing the area of Mary's bedroom minus the closet area and multiplying by carpet cost per square foot to determine the total cost.
