Oh my gosh this is driving me nuts, I just started 6th grade last week, please help...A piece of paper is 280 millimeters long and 200 millimeters wide. you want to draw a grid on the paper so that there is a whole number of squares on the paper. What are the possible sizes of the squares? What is the largest possible square?
Arghh!! I miss summer!

First, calculate the area.
280 * 200 = 56,000mm^2
Any number that will divide into that area without leaving a remainder will give you the number of whole squares.
I hope this helps. Thanks for asking.
