Using herons formula to determine the area of a triangle

The video tutorial explains how to use Heron's formula to calculate the area of a triangle when all three side lengths are known. It begins by calculating the semi-perimeter (S) by adding the side lengths and dividing by two. The instructor then demonstrates how to substitute these values into Heron's formula to find the area, using a calculator to ensure accuracy. The process involves multiplying the semi-perimeter by the differences between the semi-perimeter and each side length, followed by taking the square root of the result. The tutorial concludes with a final area calculation and a brief Q&A session.
