Question

Area of a triangle when all sides are given

Answer 1

first find s=a+b+c/2
now area=√s(s-a)(s-b)s-c)

Answer 2

Heron's formula

Step-by-step explanation:

We can find the Area of every triangle , if their sides are given .

To find Area of triangle we have to Calculate Semi-parameter (S).

Semi-parameter (S) = Sum of all three sides / 2

(S) = (a + b + c) / 2 , where a,b,c are sides of the triangle

So , Area of triangle (Using Heron's formula)

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