Solving for h involves a quadratic equation

This is a clever problem that requires the use of the quadratic formula. Try inserting a value for b into the formula and see if it works.

The key is to realize that : The total area of the figure is 80.

Therefore  h^2 + 1/2 bh = 80.

a=1  b=1/2b  c=-80. This becomes a quadratic equation to solve for h.
