Question

WAP to enter the three sides of a triangle(a,b &c) and print its area using heron's formula: s=(a+b+c)/2 area=√s(s-a)(s-b)(s-c)

Answer 1

Note: I am using C++ programming language.

#include<iostream>

#include<math.h>

using namespace std;

float CalArea(float a, float b,float c ) {

   float s = (a+b+c)/2 ;

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

   return area ;

}

int main ( ) {

   float a,b,c;

   cout<<"Enter lengths of sides of the triangle :\n" ;

   cin>>a>>b>>c;

   cout<<"\n\nArea of the triangle is " <<CalArea(a,b,c) ;

return 0 ;

}
