The answer is -6x^3+11x^2+19
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.
