1 m = 100 cm
Length of room = 10 m 50 cm = 1000 cm +50 cm = 1050 cm
Breadth of room = 9 m 60 cm = 900 cm+60 cm = 960 cm
Area of room = Length x Breadth = 1050 × 960 = 1008000cm²
Side of square tile = 15 cm
Area of square tile = Side² = 15² = 225cm²
No. of square tiles of 15cm will be required = 1008000/225 = 4480
