To solve this problem you must divide the area of the floor by the area of the sticker, then you must apply the formula for calculate the area of a rectangle, which is:
A=lw
Where l is the length and w is the width.
Therefore, you have:
A=20x10/2x1
A=200/2
A=2x10^2/2x10^0
The answer is: 2x10^2/2x10^0
