First, what do we know? We know that a box covers .9m^2. Second, what do we want to know or setting the objective. How many boxes do I need to cover 289 cm x 91 cm. Third, get from one to the other. In this case you need to either go from cm ==> m with the area or from m ==> cm for the box of tiles. You need to unify your units. I am going to go from cm ==> m. There are 100 cm in one meter. As a reminder when dividing by powers of ten move the decimal from the far right of the number in this case 289. and 91. to 2.89 and .91 respectively. Next using l x w find the area of the room. (2.89 x .91)=2.63 m^2. Now that we have common units divide to find your answer 2.63/.9 or 2.92 repeating. But you can not use just a partial box so round up to 3.
