Question

A room is 10m 50cm long and 9m 60cm wide. How many square tiles of 15cm will be required to pave it?

Answer 1

number of tiles is 4480

Answer 2

4480 tiles of 15cm will be required to pave

Step-by-step explanation:

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 = $Length \times Breadth = 1050 \times 960 = 1008000 cm^2$

Side of square tile = 15 cm

Area of square tile = $Side^2 = 15^2 = 225 cm^2$

No. of square tiles of 15cm will be required to pave = $\frac{1008000}{225}=4480$

Hence 4480 tiles of 15cm will be required to pave
