Question 702099
First let us worry about the numbers. Then we'll be concerned about what label to use. 


"72 divided by 8" also means "8 times a number gets us 72." It is called an "inverse operation" of multiplication. We can kind of say that it is the opposite of multiplication. How many times does 8 go into 72? How many times do we have to add 8 together to get 72? Both of these questions have the same answer, and both of these questions can be asked to solve this problem. 72 divided by 8 gives us 9. Now let us move on to the label.


We are given two labels: cm^2 and cm. "Squared" labels come by multiplication processes. When we multiply two measurement labels together, they usually are written with a square sign after the label. So, when we divide a squared label (as in 72 cm^2) by a non-squared label (as in 8 cm), we receive a non-squared label. Our answer should be 9 cm.
