Learn how to find the area of a triangle with 3 sides using Heron's formula, which is based on the semi-perimeter and the differences of the sides. See the derivation of the formula using cosine rule and Pythagoras theorem, and examples of different types of triangles.
In order to find the area of triangle with 3 sides, we use the Heron's Formula. Using this, the area of a triangle (A) with 3 sides a, b, and c is calculated using the formula A = √ [s (s-a) (s-b) (s-c)], where 's' is the semi-perimeter of the triangle given by s = (a + b + c)/2.
