Suppose a parallelogram has base length `\red{B \text{ UNIT}}` and height `\blue{H \text{ UNIT}}`.
What is the parallelogram's area?
K square plural_form(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`
