Illustrator artboard height & width options not showing in control panel/options bar
Hi, I am trying to modify the dimensions of an artboard per an exercise, but the instructor's options across the top have height and width boxes enabling one to make the adjustments.

Height & width are available in menu at top.
I only have the x and y dimensions available. If I go into Edit Artboards and change the dimensions, I end up with a strange result. Here is before adjusting size:

I get a white selection around the shirt, but it seems within a larger whiteboard.
How do I get the height/width options in the menu bar at the top, or another work-around to accomplish getting the blue shirt on its own artboard?
Thanks in advance.
