To convert the length of the whiteboard from feet to inches, you can use the conversion ratio of 1 foot = 12 inches.

The whiteboard is 7.5 feet long.

To find out how many inches long it is, you multiply the number of feet by the number of inches per foot:

\[
7.5 \text{ feet} \times 12 \text{ inches/foot} = 90 \text{ inches}
\]

Therefore, the whiteboard is **90 inches** long.

The correct response is **90**.
