Answer:
length of a tile = 30 cm
breadth of a tile = 15 cm
length of the hall = 3.6 m
breadth of the hall = 3 m
For a rectangular tile
Area = length × breadth
Area = 30 cm × 15 cm
Area = 450 cm²
For the rectangular hall
Area = length × breadth
Area = 3.6 m × 3 m
Area = 360 cm × 300 m
Area = 108000 cm²
No. of tiles required = Area of hall/Area of a tile
= 108000 cm²/450 cm²
= 240
therefore,240 tiles are required for the rectangular hall.
