Final answer:
Margins should be set to inches in documents.
Step-by-step explanation:
The statement 'Margins should be set to inches' is true.
When adjusting margins in a document, it is common to specify the measurement unit as inches. This allows for more precise control over the layout and formatting.
For example, in word processing software like Microsoft Word, you can set the margins in inches by going to the Page Layout tab and selecting the Margins option. You can then choose pre-defined margin sizes (such as 1 inch) or enter a custom measurement.
