Standard formula to calculate the area of a rectangle

A = l * w

where

Source Code

// C++ Program to Enter Length and Breadth of a Rectangle and Find its Area
#include <bits/stdc++.h>
using namespace std;

int main() {
    float l, w, a;

    cout << "Enter the length & width of the rectangle::\n";
    cin >> l >> w;

    // Calculate area of rectangle
    a = l * w;

    // It will print the final output
    cout << "\nArea of rectangle = " << a << " units";
    return 0;
}

Run Program

Output

Explanation

In the given program, we have taken the inputs 5 rectangle's height and 7 rectangle's width the applied the standard formula p = l * w.

Then It returned to the area 35 units value of the rectangle.
