Marjorie is designing a new set of placemats for her dining room table. She sketched a drawing
of the placemat on graph paper. The diagram represents the area of the placemat consisting of a
rectangle and two semicircles at either end. Each square on the grid measures 4 inches in length.
Find the area of the entire placemat. Explain your thinking regarding the solution to this problem.
