Carlos found that the length of the diagonal of his laptop monitor is [tex]\sqrt{290}[/tex]. If the manufacturer rounds to the nearest whole inch, what size is the monitor as measured by the diagonal?

A. 12 inches
B. 17 inches
C. 97 inches
D. 245 inches

Answer :

To find the size of the monitor measured by the diagonal, we start with the given diagonal length, which is [tex]\(\sqrt{290}\)[/tex].

1. Calculate the Diagonal Length:
- First, we need to calculate the actual length of the diagonal by finding the square root of 290. This gives us a result approximately equal to 17.03 inches.

2. Round to the Nearest Whole Number:
- Next, we'll round the calculated length to the nearest whole number. When rounding 17.03, we get 17.

Therefore, the monitor size as measured by the diagonal is 17 inches.
