Question

what is the area of triangle?

Answer 1

area of triangle = $\frac{1}{2} * base * height$ ,
   or,
$s = \frac{a + b + c}{2} [tex]area = \sqrt{s (s-a)(s-b)(s-c)}$[/tex]
  

Answer 2

It means that How much plane or How much place is covered by the Triangle.
There are two Formula to find the area of triangle:
1. 1/2(base×height)
2. √s×(s-a)×(s-b)×(s-c) in which 's' is the semi-perimeter i.e., half of perimeter of the triangle and a,b and c are sides of triangle.
