Question

The _____ is the area in Microsoft Excel where you can perform file commands such as Save, Open, and Print

Answer 1

File Button. I think it is in the left corner but I'm not sure on it 

Answer 2

I believe the answer is Backstage view
Back stage view gave you the complete command as options for users to manage our files and data in the office such as saving, print, inspecting meta data, etc. To access backstage view, you just need to click the file tab on left top corner.
