Choose any strategy to find the area of each shape below. Use the information in the Math Notes boxes for help. Assume that the shape in part (a) is a parallelogram and that the shape in part (b) is a trapezoid.
Form a rectangle using the left portion of the parallelogram. Then find the area of the rectangle.
When the trapezoid is copied and rotated, a parallelogram can be formed.
Form a parallelogram using the rotated trapezoid.
Now find the area of the parallelogram.
Use this area to find the area of the original trapezoid.
