Answer 1

Option 3: about 14 inches

Explanation:

The notebook paper is in the form of a rectangle of length

`l = 11` inches and width
`w = 8.5` inches

The diagonal of such a rectangle is given by the Pythagorean formula

`d = \sqrt{l^(2) + w^(2)}`

Substituting the values of
`l` and
`w`:

`d = \sqrt{11^(2) + 8.5^(2)}\\\\d = √(121 + 72.25)\\\\d = √(193.25)\\\\d= 13.9014\;inches`

This corresponds to Option 3: about 14 inches
