How many different arrays cam you make 30 tiles

To find out how many blue tiles Ms. Johen will need, we first need to determine the total number of yellow tiles she has used for her rectangular mosaic.

We can do this by multiplying the number of rows by the number of tiles in each row. In this case, Ms. Johen is using 12 rows of tiles with 20 tiles in each row. Multiplying these numbers together gives us:

12 rows * 20 tiles per row = 240 yellow tiles

Now, we know that Ms. Johen has 188 yellow tiles, so to find out how many blue tiles she will need, we subtract the number of yellow tiles from the total tiles used:

Total tiles used - Yellow tiles = Blue tiles needed
240 tiles - 188 yellow tiles = 52 blue tiles

Therefore, Ms. Johen will need 52 blue tiles to complete her design.
