# Heron's formula - math problems

The Heron's formula is used to calculate the contents of a general triangle using the lengths of its sides. Heron's formula states that the area of a triangle whose sides have lengths a, b, and c is:$S=\sqrt{s(s-a)(s-b)(s-c)}$

, where $s={\displaystyle \frac{a+b+c}{2}}$

is the semiperimeter (half perimeter) of the triangle .#### Number of problems found: 38
