Casey,

The first step to solve this is to draw parallelogram AMDC with AB drawn in perpendicular to CD.  Then, label all sides.  Remember, the area for a parallelogram is base * height.  The height is the AB that you were given, or 6.  The base will be CD.  But, you only have BD = 20.  If you have drawn this, however, you will see that you have right triangle ABC where BC is the rest of side CD.  Use Pythagorean theorem to find BC, add it to the 20, and that is the base.  Then, multiply that sum by the height, and you will have the area.
