This formula was derived by a Greek mathematician known as the Heron of Alexandria. However, if the altitude of a triangle is not known, and we need to find the area of triangle with 3 different sides, the Heron's formula is used.
The basic formula that is used to find the area of a triangle is ½ × Base × Height where 'Base' is the side of the triangle on which the altitude is formed, and 'Height' is the length of the altitude drawn to the 'Base' from its opposite vertex. The area of a triangle can be calculated with the help of various formulas. Using this, the area of a triangle (A) with 3 sides a, b, and c is calculated using the formula A = √, where 's' is the semi-perimeter of the triangle given by s = (a + b + c)/2. In order to find the area of triangle with 3 sides, we use the Heron's Formula.
