Question

16. Find the number of square tiles of side 12 cm, required for flooring a room of size 4 mx 5 m, will be (a) 1388 (b) 1400 (c) 1500 (d) 1600 -​

Answer 1

Answer:

Step-by-step explanation: Given :-

Area of the room 4m × 5m.

Side of the tile 20cm

Let's first calculate the total area,

4m ×5m = 20m

Now, let's find out the area of one tile,

20cm × 20cm = 400cm

Let's calculate it in meters

1 m = 100 cm

400cm = 400/100 = 4m

To find the tiles required let's divide,

20 ÷ 4 = 5 tiles.
