Question

Anyone can give me a intro about heron's formula​

Answer 1

Answer:

In geometry, Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first

Heron's formula states that the area of a triangle whose sides have lengths a, b, and c is

{\displaystyle A={\sqrt {s(s-a)(s-b)(s-c)}},}A = \sqrt{s(s-a)(s-b)(s-c)},

where s is the semi-perimeter of the triangle; that is,

{\displaystyle s={\frac {a+b+c}{2}}.}s=\frac{a+b+c}{2}.

Answer 2

Heron’s Formula, named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.

Heron’s Formula

Area of the Triangle = whole root of [s(s−a)(s−b)(s−c)]

‘S’ is the semi perimeter (half of the perimeter of the triangle)

‘a’, ‘b’, ‘c’ are the three sides of the triangle.

Hope it helps
