Using herons formula to find the area of a triangle

The video tutorial explains how to find the area of a triangle when only the side lengths are given, using Heron's formula. It begins by discussing the typical challenge of needing the height to calculate the area and introduces Heron's formula as a solution. The tutorial then walks through the steps of calculating the semi-perimeter and applying the formula to find the area, concluding with a brief Q&A session.
