In the figure below, ABCD is a parallelogram, AD = 18 and DC = 21. Segments EG and FH are perpendicular to sides of the parallelogram as shown, and EG = 16. What is the area of the parallelogram?
Area of the parallelogram = b * h = 21 * 16 (EG is the height) HF is a smoke screen in this problem....not needed.
