find the area of a square in csharp

To find the area of a square in C#, you need to multiply the length of one side by itself. Here's some example code:

main.cs
int sideLength = 5; // length of one side of the square
int area = sideLength * sideLength; // calculate area by multiplying side length by itself
Console.WriteLine("The area of the square is: " + area); // output result

In this example, the length of one side of the square is set to 5. The code then calculates the area by multiplying the side length by itself. The result is output to the console, which in this case would be "The area of the square is: 25".
