Using heron's formula to find the area of a triangle

The video tutorial explains how to find the area of a triangle using Heron's formula. It begins by introducing the problem of calculating the area with given side lengths and then explains Heron's formula, which involves calculating the semi-perimeter and using it to find the area. The tutorial provides a step-by-step guide to applying the formula, including calculating the semi-perimeter and substituting values into the formula. The video concludes with a reminder that the formula will be provided on a reference sheet.
