A surveyer wants to know the area of a region that is 212212 miles by 314314 miles. Which expression can be used to find the area in square miles?

Question

It wants you to create a model about the area and the region between 2 1/2 square miles and 3 3/4 square miles.

Answer 1

One way to do this is decimally, i.e. 2.5 miles times 3.75 miles.

 

Another way is to convert each number to an improper fraction, i.e. 5/2 times 15/4.

 

"Which expression can be used..." implies that this is a multiple choice question, but you did not include those choices.
