9600 rectangular tiles of dimensions 15 cm x 10 cm will be required to cover the floor of a square ground whose side is 12 m.

Step-by-step explanation:

Given, rectangular tiles of dimensions 15 cm x 10 cm.

Area of the each tile = 15 cm x 10 cm = 150 cm²

Side of a square floor = 12 m

1 m = 100 cm

12 m = 12 x 100 cm = 1200 cm

Area of the square floor = 1200 x 1200 cm² = 1440000 cm²

Number of tiles required to cover the floor = \frac{1440000}{150} = 9600

Hence, 9600 rectangular tiles of dimensions 15 cm x 10 cm will be required to cover the floor of a square ground whose side is 12 m.
