Design dark coloured

3x3 4
4x4 8
5x5 12

4 + 8 + 12 = 24 dark tiles

To find out the number of dark-colored tiles required for the reception area, we need to determine the area of the tiles and the area of the reception area.

1. Calculate the area of the reception area:
Area = Length x Width
Area = 18 x 18
Area = 324 square units

2. Determine the size of the tiles:
The question does not provide information about the size of each tile. It only mentions that the tiling company specializes in multi-color tile patterns. Without knowing the size of the tiles or the pattern, it is not possible to determine the number of dark-colored tiles.

To answer the question accurately, we need more information about the size or dimensions of the tiles, or any specific pattern instructions for tiling the reception area.
