Answer 2

The length of the book rack in centimeters and millimeters​ is 215 cm and 2150 mm.

• The length of the book rack is given in meters which are 2.15m

• 2.15  is in decimal form so when we convert it into fraction form we get 215/100 meters.
• There are 100 cm in 1 meter, Therefore, in 2.15 m we have $215/100*100 =215 cm$
• Similarly, there are 1000 mm in 1 meter. Therefore, in 2.15m there will be  $215/100 *1000= 2150 mm$
