Problem:
Write a program to calculate area and perimeter of a triangle.
Solution:
#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
float pr,ar,a=4,b=5,c=9,h=5.2;
pr=a+b+c;
ar=1/2*b*h;
cout<<"the area of triangle is:"<<ar<<endl;
cout<<"the perimeter of triangle is:"<<pr<<endl;
getch();
}
#include<conio.h>
using namespace std;
int main()
{
float pr,ar,a=4,b=5,c=9,h=5.2;
pr=a+b+c;
ar=1/2*b*h;
cout<<"the area of triangle is:"<<ar<<endl;
cout<<"the perimeter of triangle is:"<<pr<<endl;
getch();
}
Output:
