In the figure below, ABCD is a parallelogram, AD = 18 and DC = 27. Segments EG (which is a repeating decimal) and FH  (which is a repeating decimal) are perpendicular to sides of the parallelogram as shown, and EG = 16. Determine FH.

Since DC  can be considered as one base of parallelogram   ABCD  and  EG is the height drawn to this base.....the area  is  DC * EG =  27 * 16  = 432 units^2

But BC  can be considered as another base  and  FH  is a height drawn to this base....and since the area is constant......we have that

432  = BC * FH     but   AD  = BC  = 18  ....so....

432  = 18 * FH      divide both sides by 18

24  = FH
