Question

what is heron's formula ​

Answer 1

In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.

Answer 2

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.
