Write a program to accept three sides of a triangle and transfer them to a function to compute the area of a triangle.

#include /*header file*/

#include /*header file*/

float tri_area(float a,float b, float c); /* new function*/

main() /*main function*/

{

{

float s1,s2,s3,area;

printf(“

Enter the three sides of a triangle”);

scanf(“%f%f%f”,&s1,&s2,&s3);

area=tri_area(s1,s2,s3);

printf(“

Area of triangle is : %f square units.”, area); /*printing area*/

}

float tri_area(float a,float b,float c)

{

float s, area;

s=(a+b+c)/2;

area=sqrt(s*(s-a)*(s-b)*(s-c)); /*hero’s formula*/

return(area);

}

}
