Question

Answer 1

Answer:

2160

Step-by-step explanation:

Number of tiles = area of floor/ area of a tile

= 1200 * 900 / 25 * 50

= 2160

Answer 2

2160 tiles are required to cover floor

Step-by-step explanation:

Length of tile = 25 cm

Breadth of tile = 20 cm

Area of tile = $Length \times Breadth = 25 \times 20 = 500 cm^2$

1 m = 100 cm

Length of floor = 12 m = 1200 cm

Breadth of floor = 9m = 900 cm

Area of floor =$Length \times Breadth = 1200 \times 900 =1080000$

No. of tiles required = $\frac{1080000}{500}=2160$

Hence 2160 tiles are required to cover floor.
