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
