How to find the area of a triangle using heron's formula

The video tutorial explains how to find the area of a triangle using Heron's formula, especially when the height is not given. It starts with a recap of the basic area formula (1/2 base times height) and introduces Heron's formula for cases where only side lengths are known. The tutorial walks through the steps of calculating the semi-perimeter and using it in Heron's formula, providing a detailed example calculation. The importance of showing work to identify mistakes is emphasized, and the session concludes with a brief Q&A.
