$\sqrt[ |?| ]{?}$
​

Answer 1

Answer:

formula of herons formula:

√s(s-a)(s-b)(s-c)

where S ( semiperimeter) = (a+b+c)/2

Answer 2

Answer:

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

Δ = $\sqrt{(s)(s-a)(s-b)(s-c)}$              ; where  a,b,c are sides

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

                                                                 and Δ = area of the triangle.
