Answer 1

Answer:

Answer is 240 tiles.

Step-by-step explanation:

Length of the rectangular = 144 cm

Breadth of the rectangular = 100 cm

Area of the rectangular = Length * Breadth

144cm*100cm=14400 cm square.

Length of tile= 12cm

breadth of tile= 5cm

Area of tile= Length * Breadth ,,,,, 12*5= 60 cm square.

No. of tiles= Area of rectangular/ Area of tiles

tiles = 14400/60 = 240 tiles.

Hence, the answer is 240 tiles.
