A Program to Find the Area of a Rectangle

In this example, we are giving a program to find the area of a rectangle. The rule of finding the area of a rectangle is: A = width * height.

Program to find the area of a rectangle:

#include <iostream>
#include <cmath>
using namespace std;
int main() {
  float w, h, area;
  cout << "Enter the value of width and height: " << endl;
  cin >> w >> h;
  area = w * h;
  cout << "Area of rectangle: " << area;
  return 0;
}

Output:

Enter the value of width and height: 3, 4
Area of rectangle: 12.00
