How do i fit a square around a point in an image?

I have the image:

    I = [1 1 1 3 3 3 3 3
         1 1 1 1 3 3 3 3
         1 1 1 1 3 3 3 3
         1 1 1 1 2 2 2 3
         1 1 1 1 2 2 2 3
         1 1 1 1 2 2 2 3
         1 1 1 1 2 2 2 2];

How can i fit a square of size say two pixels around the point (4,6)? Many thanks for your help/suggestions.

If you are asking to draw a square on the screen then use rectangle()

"i fit a square of size say two pixels"

"my actual intention is to get the area of the square"

So if your square is 2 pixels by 2 pixels, then your area will be 4 pixels. Why do you even need to ask?
