Microsoft Word Page layout questions?

I'm a typing a business report/term paper for school. I've written my report (protrait layout) and need to include some graphs. The graphs don't fit under portrait layout and need to be in landscape. Is it possible to configure it so that there is two different formats (i.e. pages 1-7 portrait layout, pages 8-11 landscape format)? Its being submitted electronically so using two different docmuents and printing them out isn't an opition.
