# Answer to Question #48743 in C++ for ama

Question #48743

Given the lengths a,b,c of the sides of triangle, write a function based program to compute the area of the triangle., The formula for computing the area is given by:

Area = √ s(s-a)(s-b)(s-c)

where s is the semiparameter of the triangle

s=(a+b+c)/2

Area = √ s(s-a)(s-b)(s-c)

where s is the semiparameter of the triangle

s=(a+b+c)/2

Expert's answer

#include <cstdlib>

#include <iostream>

#include <math.h>

using namespace std;

float Area( 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; // lengths of sides

cout << "Enter a: ";

cin >> a;

cout << "Enter b: ";

cin >> b;

cout << "Enter c: ";

cin >> c;

printf("The area of triangle is: %3.2f\n", Area(a,b,c)); //call of the function and print result

system("PAUSE");

return EXIT_SUCCESS;

}
