Jia is tiling a floor. the floor is a square with side
length 12 feet. jia wants the tiles to be squares
with side length 2 feet. how many tiles does jia
need to cover the entire floor? note that the area
of a square is s? , where s is the side length. explain.

36 tiles

Step-by-step explanation:

First, find area of the square floor knowing the formula as;

Area=

where s= side of a square.

If one side of the floor is 12 feet, then Area=

Next, find the area of each tile using the same formula and given s=2 feet;

Area(tile) =

To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles
