Answer:
I'm not entirely sure, but I think since you're dealing with area, that changes the way you'd do the math.
Step-by-step explanation:
Since centimeters will have a larger number than meters, that being a number 100x larger, the area is gonna appear a lot bigger. Let's say you have a tile that's 2cm x 4cm with an area of 8cm^2. If you double the sides to 4cm x 8cm, your area will quadruple to 32cm^2.
I think that's what is happening in terms of your problem.
