About Me

- I'm a high-school math teacher completely frustrated with new math, reform math, fuzzy math, the color of math, talking about math, literacy across the curriculum and all those other things that get in the way of students actually learning math, not to mention the ever-present "You need to help raise our scores by taking one day a week to go over test-taking skills" and other administrative folderol.

It is pleasing that my answer agrees with the other commenter, but...
there has to be a better way.
I thought about Heron, but the subtractions looked messy.
I dropped an altitude, wrote two pythagorean equations, solved for the position of the altitude on the base, then for the altitude, then for the area.
Can I jump quicker to the end? Clean things up? Or the neatest approach is entirely different?
