# Heron's formula - practice problems

The Heron's formula is used to calculate the area 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=s(s−a)(s−b)(s−c) $, where $s=2a+b+c $ is the semiperimeter (half perimeter) of the triangle .
