Jia is tiling a floor. The floor is a square with side

NNADVOKAT [17]

Answer:

36 tiles

Step-by-step explanation:

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

Area= $s^{2}$

where s= side of a square.

If one side of the floor is 12 feet, then Area= $12^{2} = 144ft^{2}$

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

Area(tile) = $2^{2} = 4ft^{2}$

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
