Question

If I have a room that is 4 by 4 , and I am pucrchasing tiles that are 1/3x1/3, calculate the number of tiles needed to cover the area in square meters. Show math please The room is in sqaure meters, and the tiles are in meters

Answer 1

144 tiles

Explanation:

The room is
`16cm^(2)` because 4 by 4 is 4 x 4 = 16.

Each tile is
`(1)/(9)` because
`(1)/(3)` x
`(1)/(3)` =
`(1)/(9)`.

So we must do 16 ÷
`(1)/(9)` = 144

So 144 tiles are needed.
