Answer:
4 tiles
Step-by-step explanation:
If the width is 84 cm, let's take a 84cm lengthed tile.
in the remaining part we get 112-84=28 cm
let's check whether 84÷ 28 is a whole number. if it's a whole number we can keep the n number of 28 cm length tile
84÷28=3
luckily we dont need to think a lot. just put 3, 28 cm tile in the balance part .
she only needs 4 tiles to fill the table
