Answer 2

Answer: There are 400 white tiles which Ron will need.

Explanation:

Since we have given that

Number of rows to cover the counter = 8

Number of tiles to cover each 8 rows = 54 square tiles

So, total number of tiles to cover 8 rows is given by

`8* 54=432`

Number of groups on which 4 blue tiles are placed = 8

Total number of blue tiles on 8 groups is given by

`8* 4=32`

Remaining are the white tiles so, it is given by

`432-32=400`

So, there are 400 white tiles which Ron will need.
