Question

The Heron's formula to find the area of a triangle is:

• A. $\sqrt{s(s-a)(s-c)}$
• B. $\sqrt{s(s-a)(s-b)(s-c)}$
• C. $\sqrt{(s-a)(s-b)(s-c)}$
• D. $\sqrt{s(s-b)(s-c)}$

Answer 1

The correct option is B

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

The Heron's formula to find the area of a triangle is:

$ar\left(△\right)=\sqrt{s(s-a)(s-b)(s-c)}$

$a,b\&c$ are the sides of the triangle and $s$ is the semi - perimeter, $s=\frac{a+b+c}{2}$.
