Final answer:
Finn should change the page orientation to landscape in his word processor to switch from an 8.5-inch x 11-inch to an 11-inch x 8.5-inch page format.
Step-by-step explanation:
To change an 8.5-inch x 11-inch page format to an 11-inch x 8.5-inch page format, Finn needs to change the page orientation to landscape. This task does not require changing the page size to A4, rotating the content 90 degrees, or adjusting margins and columns specifically. Instead, changing the orientation to landscape will automatically adjust the layout of the content to fit within the desired dimensions.
Most word processors, such as Microsoft Word, make this an easy task. Finn simply needs to look for the Page Layout or Layout menu and then select Orientation, choosing the landscape option. Once this is done, the document will be displayed as an 11-inch wide by 8.5-inch tall page.
To change the document from 8.5-inch x 11-inch to 11-inch x 8.5-inch page format, Finn can accomplish this task by changing the page orientation to landscape. This will rotate the contents of the document 90 degrees counter-clockwise, allowing the document to fit the new page format.
