Write a C program for evaluating the area of triangle using the formula sqrt(s(s-a)(s-b)(s-c)).

 AIM: To write a program for evaluating the area of triangle using the formula sqrt(s(s-a)(s-b)(s-c)).

ALGORITHM:

Step1: Start the program.

Step2: Get the inputs a, r, t and s. 

Step3: Calculate s = (a+b+c) / 2.

Step4: Calculate area=sqrt(s*(s-a)*(s-b)*(s-c)). 

Step 5: Print the result „area‟.

Step 6: Stop the program.

PROGRAM:

#include<stdio.h> 

#include<math.h> 

void main()

{

int a,b,c; 

float s,area; 

clrscr();

printf("Enter the values of a,b,c: "); 

scanf("%d%d%d",&a,&b,&c); 

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

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

printf("The area of a triangle is =%f",area); 

}

OUTPUT:

Enter the values of a,b,c: 10 20 30 

The area of a triangle is = 0.000000

RESULT:

Thus the C program to find the area of triangle using the formula sqrt(s(s-a)(s-b)(s-c)) has 

been successfully executed and verified.
