Question

in heron's formula, whichis used to find area of triangle, what is represented by's'?​

Answer 1

Answer :

In heron's formula, "s" is semi perimeter of triangle.

We can find it by finding half of the sum of all sides of triangle or by finding half of perimeter of triangle.

Mathematically :

$\sf s = \dfrac{a + b + c}{2}$

or

$\sf s = \dfrac{perimeter}{2}$

Know more :

Heron's formula :

$\sf Area =\sqrt{s(s-a)(s-b)(s-c)}$

where,

s = semi-perimeter

a = length of side a

b = length of side b

c = length of side c
