As you probably know, the metric system is much easier to understand as it is based on factors of 10. 1 meter is equal to 100 centimeters. You'll see that you multiply by 100. So, to the problem, we're going to first figure out our conversions. To easily multiply by 100, move the decimal spot over 2 to the right (__ 0's = __ moves over). Now our 'new' equation is "225 centimeters long and 180 centimeters wide". This is where we multiply. 225x180= 40,500 cm². Congratulations, you finished your problem. Make sure you put your LABEL DOWN TOO!! VERY IMPORTANT!!
