In the figure below, ABCD is a parallelogram, AD= 18 and DC=27. 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 a parallelogram is base times height.
base is DC and height is EG, or 16 * 27 = 432
all that other data is not needed.
