can photoshop tell me the amount of square inches that will actually be printed?

Here's a question for you - if I have an image on a 13x19 digital canvas(workspace), can Photoshop tell me the amount of square inches that will actually be printed? 

[Damien Symonds]

Can't mathematics tell you that?  13x19=247 square inches.

I fear I might be missing the essence of this question.
