Question

describe heron's formulas

Answer 1

herons formula is used to calculate area of any triangle either it is scalene,equilateral or right angle triangle.

here we required only length of three sides

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

where s is semi perimeter

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

hope this will help you

Answer 2

heyaa,,,
______________________________
to calculate area of triangle ;
at first you need to calculate S.
s = (a+b+c)/2
now, from herones formula;
area,=√s(s-a)(s-b) (s-c)
