There's a better proof.. http://www.artofproblemsolving.com/Resources/articles.php (Look for heron's formula)

Woah but its still a fairly advanced proof involving complex number geometry, but I love it! And Agnishom, the author of the MathIsFun proof intermediately proves the law of cosines which is a step in the most common proof presented with Heron's formula.

There was another method of proving it.. it was in AoPS precalc.
