What is the heroes formula?
Its heron's formula - It is used for finding the area of a triangle.√s(s-a)(s-b)(s-c) where, s = Semi - perimeter of trianglea,b,c = sides of triangle
HERO'S FORMULA-:
\(area \: of \: = \: \sqrt{s(s - a)(s - b)(s - c)} \\ \\ where \: a \: b \: and \: c \: are \: side \: of \: triangle \: and \: \\ \\ s = \frac{a + b + c}{2} \\ s \: is \: the \: half \: perimeter \: abc\)
