write the thron's formula for as of triangle
Answers
Step-by-step explanation:
Hero of Alexandria was a great mathematician who derived the formula for the calculation of the area of a triangle using the length of all three sides. It is also termed as Hero’s Formula. He also extended this idea to find the area of quadrilateral and also higher-order polygons. This formula has its huge applications in trigonometry such as proving the law of cosines or law of cotangents, etc.

Heron’s Formula For Area of Triangle
According to Heron, we can find the area of any given triangle, whether it is a scalene, isosceles or equilateral, by using the formula, provided the sides of the triangle.
Suppose, a triangle ABC, whose sides are a, b and c, respectively. Thus, the area of a triangle can be given by;
Area=s(s−a)(s−b)(s−c)−−−−−−−−−−−−−−−−−√
Where “s” is semi-perimeter = (a+b+c) / 2
And a, b, c are the three sides of the triangle.
