Remodeling a closet floor with floor tiles:1. My original closet was 2ft by 2 ft. I had to put down floor tiles and add trim around the edge of the floor. How much trim did I need to buy? 8ftHow many 1 square foot floor tiles did I need to buy?12

2. I decided to expand my closet and double its size. Trim needed? 16 ftNumber of floor tiles? 16.

Notice that by doubling the size of my closet, I simply needed to buy double the amount of trim. (Perimeter was just doubled, too). Perimeter: Simply multiply by your scale factor to find your new perimeter.

But, the number of floor tiles (area) I needed to purchased was NOT just doubled. It was 4 times as many. This is because both the length and width were doubled, and then those doubled numbers were multiplied. Area: Multiply by your scale factor TWICE to find your new area.
