Parallelogram Area

Move point A or point B to create a parallelogram of your choice. Drag point K to the extreme right of the segment.
1.) What is the relationship between the area of the original figure (parallelogram) and the area of the resulting rectangle? 2.) In terms of b and h, what is the area of the parallelogram? the rectangle? 3.) Based on questions 1 and 2, what conjecture can you make about the two figures?
