How do I calculate the area around a given point-CodePudding

Let's say I have the coordinates 0, 0 as my center point. And I want to calculate an area that extrudes 6 tiles (1 tile being 1 unit) each direction from the center point, essentially building a rectangle that's 13x13 based on the center point.

This is what I have, but I feel as if that's not correct.

class Program
{
    static Point AbsPos = new Point(0, 0);
    static Point Rectangle;

    static void Main(string[] args)
    {
       Rectangle = new Point(AbsPos.X * 13, AbsPos.Y * 13);
    }
}

CodePudding user response：

For a grid of same-shaped tiles, the location of the center of a square has no influence on its area. A 13x13 square has an area of 169 regardless of whether it's located at 0,0 or 17,22. If your user is going to give you 6 as an input then you simply need to do:

Console.WriteLine(Math.Pow((2 * input)   1, 2));
