Heron's formula (example and proof)

How can we find the area of the triangle with 3 given sides? In this geometry tutorial, we will see how to use Heron's formula to find the area of the triangle whose sides are 11, 13, and 20. Note that this is also a "Heronian triangle" because both its sides and area are positive whole numbers. We will also learn the proof of the formula.
