Object dimensions in tray

I would like to know if there is a window that would show an object dimensions
example when selecting a 4’ x 4’ square. I could see these dimension of a tray?
I can see the area, but not with and height dimensions.
Any advice would be appreciated.

Entity Info will give you the length of a selected edge or the area of a selected face/surface but not the length/width. You can measure the lengths with the Tape Measure tool or the Dimension tool.

or the text (label) tool
