This lesson focuses on the area of polygons. Students reviews finding the area of rectangles and extends this to finding the area of any parallelogram. They then draw parallelograms and find the side lengths given information about the area. Next, students find the area of irregular figures that can be divided into parallelograms. They then solve triangle area problems and calculate the areas of various polygons including trapezoids.
