The video tutorial explains how to find the area of a triangle using Heron's formula, which is useful when only the side lengths are known. The instructor provides three examples, demonstrating the step-by-step process of calculating the semi-perimeter and using it in Heron's formula to find the area. The tutorial concludes with approximations of the results and emphasizes the straightforward nature of the method.
