B * H
Suppose a parallelogram has base length B \text{ UNIT} and height H \text{ UNIT}.
What is the parallelogram's area?
K
square plural(UNIT_TEXT)
graph.p = parallelogram(B, H, UNIT, SH);
graph.p.drawBase();
graph.p.drawHeight();
By moving a slice of the parallelogram, we can see that its area is equal to that of a rectangle with the same base and height.
graph.p.sliceHint();
graph.p.animHint();
area of rectangle = b \times h
graph.p.drawArea();
A = B \times H = K
