There's a better proof.. http://www.artofproblemsolving.com/Resources/articles.php (Look for heron's formula) Taehyung Kim · 3 years, 9 months ago

@Taehyung Kim 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.
