Question

9. A rectangular floor is 12 m long and 10 m broad. The floor has to be covered with smaller rectangular tiles, each of which is 20 cm long and 20 cm broad. Find the number of tiles required to cover the floor.​

Answer 1

Answer:

3000

Step-by-step explanation:

we have total area to be covered as 12 * 10 which is 120 M2 let's convert this to cm2 so it will be 1200000 cm2 now area of each tile is 400 cm2

so divide each other and u will get ans to be 3000

Answer 2

Answer: 3000 tiles will be required to cover the floor.

Step-by-step explanation:

Area of the rectangular floor = L X B

= 12 m X 10 m = 1200 cm X 1000 cm = 12,00,000 $cm^{2}$

Area of 1 smaller rectangular tile = L X B

= 20 cm X 20 cm = 400 $cm^{2}$

Number of smaller rectangular tiles required to cover the floor

= Area of floor / Area of smaller rectangular tile

= $\frac{1200000}{400}$

= 3000 tiles
