Question

Write the formula derived by Heron for area of triangle and explain each letter of it

Answer 1

area of triangle =√s×(s-a)×(s-b)×(s-c)

Answer 2

Helen's formula =

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

Where s is the semi-perimeter which is calculated by the formula =

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

a is the first side....

b is the second side ....

c is the third side ....

s - a means semi-perimeter - first side ...

s - b means semi-perimeter - second side ...

s - c semi-perimeter - third side ...
