Question

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.

Answer 1

36 tiles

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
