Answer 2

Answer:  Length of notebook in centimeters is 27.94 cm.

Step-by-step explanation:

Since we have given that

The width of a desk = 25 inches

There is given that 25 inches = 63.5 centimeters

As we have given that the measurement in inches varies directly with a measurement in centimeters.

So, we have mention that

If length of notebook  = 11 inches

Let the length of notebook in centimeters be 'x'.

According to question, it becomes,

$\frac{25}{63.5}=\frac{11}{x}\\\\25\times x=11\times 63.5\\\\x=\frac{698.5}{25}\\\\x=27.94\ cm$

Hence, Length of notebook in centimeters is 27.94 cm.
