Question

Write a c program to find area of a triangle area of triangle=(s(s-a)(s-b)(s-c)).Where a, b and c are three sides of the triangle and s=(a+b+c)/2.

Answer 1

/* C Program to find Area of a Triangle and Perimeter of a Triangle */

#include<stdio.h>

#include<math.h>

int main()

{

float a, b, c, Perimeter, s, Area;

printf("\nPlease Enter three sides of triangle\n");

scanf("%f%f%f",&a,&b,&c);

Perimeter = a+b+c;

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

Area = sqrt(s*(s-a)*(s-b)*(s-c));

printf("\n Perimeter of Traiangle = %.2f\n", Perimeter);

printf("\n Semi Perimeter of Traiangle = %.2f\n",s);

printf("\n Area of triangle = %.2f\n",Area);

return 0;
