TOP/Collection of Mathematical Formulas/Area
Manage Bookmarks
We will calculate the area of a triangle using Heron’s formula based on its three sides.
Side length a
Side length b
Side length c
Area S 
\(\normalsize Triangle\ by\ Heron's\ formula\\ (1)\ area:\ S=\sqrt{s(s-a)(s-b)(s-c)}\\ \hspace{140px} s={\large\frac{(a+b+c)}{2}}\\\)
