Ans.

 /*Program to area of triangle using Heron's Formula*/
 #include<stdio.h>

 #include<conio.h>
 #include<math.h> 

 int main()

 {

  int x=10,y=8,z=7;
  float s=0.0;

  double area=0;

  s=(x+y+z)/2.0;
  area=(s*(s-x)*(s-y)*(s-z));

  printf("\nArea of triangle = %lf",area);
  getch();
  return 0;

 }

/**************OUTPUT***************
