Tiled floor with 225 square tiles means the area of the square room is 225.
Formula needed: A = (side)^2 or in short
A = s^2.
We need to find s.
225 = r^2
sqrt{225} = sqrt{r^2}
15 = r
There are 15 tiles are along an edge of the room.
The simplification is 20x-15 because 2 times 6x is 12 x and plus the 8 x its 20 then 2 times -5 is -10 plus the other - 5 is -15
