How to draw a square with specific plot points

I’m trying to create two squares, one larger one, and the other within it.

I attempted to create one using matrices. I create one with x = [0 0 1 1] and y = [0 1 1 0]

I wanted a line to connect each one of the points, to thus create a line. However, when I did that, I only received three lines connect between the dots for some reason. The bottom points (0,0) and (1,0) for some reason were not connected. I then attempted to make a second square, and the same thing happened, with the two lower points in regards to their Y points did not connect. I tried using the rectangle function as well, but can’t get a square within a square to appear. Any help would be great. ThanksI’m trying to create two squares, one larger one, and the other within it.
