The product of the base and height of a rectangle is the area. can this statement be represented as a direct variation for the base and height? (hint: treat the area as a constant.)

Look at the formula A = b(h):  Area of a rect. = base times height.

In the unusual situation where you'd hold the area constant and vary b and h, then   A=bh could be re-written as

 A
= h    or  A/h = b.  In both cases we'd be working with inverse proportion,
 b                                   not direct proportion / variation.
