Heron s Formula Find Area of a Triangle Using Lengths of Its Sides ( Example, Formula Derivation)

Herons formula enables us to find the area of a triangle using just the lengths of its sides. It states that if a, b, and c are the sides of a triangle, and s its semiperimeter, then the area of the triangle is equal to the square root of s(sa)(sb)(sc). In this video we start with a problem that can be solved using Herons formula. We then derive Herons formula, and use it to solve our problem.
