Area of Triangles using Heron's Formula

Calculating area when the height is unknown, focusing on the derivation and application of the semi perimeter method.

Key Questions

  1. 1When is Heron's formula more efficient than the standard half base times height formula?
  2. 2How does the semi perimeter relate to the overall dimensions of the triangle?
  3. 3Can Heron's formula be used to find the area of a quadrilateral if we know its diagonal?
