find the area of a rectangle in csharp

Here's a C# code snippet to find the area of a rectangle using the formula length * width:

main.cs
int length = 5;
int width = 3;
int area = length * width;
Console.WriteLine($"The area of the rectangle is {area}");

In this example, we declare two integer variables length and width to represent the dimensions of the rectangle. We then calculate the area by multiplying length by width and store the result in the area variable. Finally, we use Console.WriteLine() to print out the result.
