Question

02. What is Heron's Formula?Also write the meaning of symbols used in this formula​

Answer 1

Answer:

√s(s-a)(s-b)(s-c)

s is the the semi-perimeter of the triangle which is = perimeter of the triangle /2

a,b and c are the three sides of the triangle

Answer 2

Heron’s formula is used to find the area of a triangle when we know the length of all its sides. It is also termed as Hero’s Formula. We don’t have to need to know the angle measurement of a triangle to calculate its area.

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=

$\sqrt{(s - a)(s - b)(s - c)}$

Where “s” is semi-perimeter = (a+b+c) / 2

And a, b, c are the three sides of the triangle.
