How to use heron's formula to find the area of a triangle with SSS

The video tutorial introduces Heron's formula, a method to find the area of a triangle when only the side lengths are known, without needing angles. The instructor explains the limitations of previous methods that required angles or height and introduces Heron's formula as a solution. The process involves calculating a semi-perimeter (S) and then using it in the formula to find the area. The tutorial includes a step-by-step example calculation, emphasizing the importance of remembering the formula and understanding its application.
