Answer 1

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

The whiteboard is 7.5 feet long. To find the length in inches, you can multiply the length in feet by the number of inches per foot:

\[ \text{Length in inches} = 7.5 , \text{ft} \times 12 , \text{in/ft} \]

Calculating this:

\[ \text{Length in inches} = 7.5 \times 12 = 90 , \text{in} \]

So the correct answer is B) 90.
