➤ Program to calculate area of triangle without using Heron's formula .
#include<stdio.h>
int main()
{ float a,b,area;
printf("Enter base and height of triangle: ");
scanf("%f%f",&a,&b);
area=(a*b)/2;
printf("Area=%.2f",area);

}
OUTPUT :
Enter base and height of triangle
Enter base and height of triangle: 4 2
Area=4.00

int main()
{ float a,b,c,s,area;
printf("Enter three sides of triangle: ");
scanf("%f%f%f",&a,&b,&c);
s=(a+b+c)/2;
area=sqrt((s*(s-a)*(s-b)*(s-c)));
