// How to Find the Perimeter of a Rectangle in C# Program
using System;

public class W3CW {
    static public void Main (string[] args) {
        Console.WriteLine("Enter the length & width of the rectangle::\n");
        float l=Convert.ToInt32(Console.ReadLine());
        float w=Convert.ToInt32(Console.ReadLine());
        
        // It will calculate the perimeter of the rectangle
        float p = 2 * (l + w);
        
        // It will print the final output
        Console.WriteLine("The Perimeter of rectangle = "+p+" units");
    }
}

Run

Output

Explanation

In this program, we have taken two inputs from the user rectangle's width 9 and rectangle's height 8.

Then used the standard formula P = 2(l + w) to calculate the perimeter of a rectangle then it will return the 34 units the perimeter of the rectangle.
