Mr.Snider is tiling a floor.The floor is 16 tiles long and 9 tiles wide.The center section is tiles12 tiles long and 5 tiles wide. How many tilesate in the border section?

9-5 = 4 along sides for entire length of floor so 4 *16 for sides

ends are 16-12 = 4 by 5 = 20

4*16 + 20 = 84

To find the number of tiles in the border section, we first need to calculate the total number of tiles in the entire floor. Then, we subtract the number of tiles in the center section from the total to get the number of tiles in the border section.

The floor is 16 tiles long and 9 tiles wide, so the total number of tiles in the entire floor is obtained by multiplying these two dimensions:

Total number of tiles = Length * Width = 16 tiles * 9 tiles = 144 tiles

The center section is 12 tiles long and 5 tiles wide, so the number of tiles in the center section is:

Number of tiles in center section = Length * Width = 12 tiles * 5 tiles = 60 tiles

Finally, we can find the number of tiles in the border section by subtracting the number of tiles in the center section from the total number of tiles:

Number of tiles in border section = Total number of tiles - Number of tiles in center section
= 144 tiles - 60 tiles
= 84 tiles

Therefore, there are 84 tiles in the border section.
