Mike began tiling his bathroom floor. he completed the top edge and left edge of the floor. each piece is a square that has a side length of 2 1/2 inches. what will be the area of the completed floor when mike is finished?

First, you need to find the length of each edge. So, you do 2 1/2*6 and 2 1/2*9.
After doing that, you get 15 for the left edge and 22.5 for the top edge. Finally, to find area, you do 15*22.5, which is our answer, 337.5 square inches.

Sorry if I'm wrong XD
