Answer:

9 tiles.

Step-by-step explanation:

It is given that the shape of covering area is square, this means all sides are equal. If Nina fits 3 color tiles across the top of the square, it means each side would be the same. Nina use 3 columns and 3 rows to fill the square.

To fill the square area Nina needs 3 × 3 = 9 tiles

Nina would use 9 tiles in all.
