Write a a program to find the area of a triangle.

Formula of area of any triangle:
Area = √(s*(s-a)*(s-b)*(s-c))
Where s = (a + b + c)/2
Output:
Enter size of each sides of the triangle: 2 4 5
Area of triangle is: 3.800

Code:
#include<stdio.h>
#include<math.h>
int main(){
float a,b,c;
float s,area;

printf("Enter size of each sides of triangle");
scanf("%f%f%f",&a,&b,&c);

s = (a+b+c)/2;
area = sqrt(s*(s-a)*(s-b)*(s-c));

printf("Area of triangle is: %.3f",area);
return 0; }
