Portrait and Landscape take their names from the way paintings of those two types are. Both are rectangular, but a portrait is usually higher than it is wide and a landscape is wider than it is high. As printing paper is rectangular too, portrait and landscape determine which way on the page spreadsheets, or other types of documents, are printed. Portrait is the standard way, but sometimes you may want to have things printed in landscape mode, so you will want to see how it looks before printing. That is where portrait and landscape views come in.
You can not change a paper size to landscape, landscape is an orientation, not a size.

To change the print orientation from portrait to landscape, go to the settings of the document or printer properties and select landscape orientation. This adjustment will modify the way the content is printed on the page, switching it from vertical to horizontal layout.
If you mean that you want your pages to be turned by 90 degrees do this: File - Page setup - then pick "landscape".
