Letting be the semiperimeter of the triangle, = (+ +), 2, · You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that has been known for nearly years. Constructions for proving Heron’s theorem are included as are two extensions and a practice worksheet. It is stated as: Area of a triangle = ss a s b s c() () ()− − − (I) Heron (C.E. The lab has students find the area using three different methods: Heron’s, the basic formula, and then using Cabri. His formula states: K = s(s − a)(s −b)(s − c) Where a, b, and c, are the lengths of the sides and s is the semiperimeter of the triangle. As per Heron's formula, the value of the area of any triangle having lengths, a, b, c, perimeter of the triangle, P, and semi-perimeter of the triangle as This formula works for the most basic of triangles and works if you are provided with the sides of the triangle.
