Question

chapter 12 heroine ka sutra​

Answer 1

Answer:

The Heron's formula is used to calculate the area of triangle.

You can calculate the area of triangle if you know the length of the side.

Consider the figure 1.

First we need to calculate "s" (The value of s is half of the perimeter).

$s=\frac{a+b+c}{2}$

Now calculate the area as:

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

Hence, to find the area of the triangle by using the Heron's formula first calculate the value of s and then plug it into the formula $A=\sqrt{s(s-a)(s-b)(s-c)}$.
