Question

what is Herons Formula?

​

Answer 1

$\bf \huge \pink{Answer}$

Heron's formula is to get are of scalene triangle[√ (s)(s - a)(s-b)(s-c)

where s is semi-perimeter (half of the total perimeter of the triangle )

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

Answer 2

Answer:

${\huge {\purple {\mathcal {\underline {\overline {\boxed {Answer :}}}}}}}$

Area of triangle using three side

$s = \sqrt{ \: s(s−a)(s−b)(s−c) \: \: }$

Semiperimeter, s = Perimeter of triangle/2 = (a+b+c)/2
