Question

A rectangular hall has a length of 14m and breadth of 12m. How many
Square tiles with sides of 10cm
are needed to cover the floor
the hall?​

Answer 1

Answer:

16800 tiles...

Step-by-step explanation:

10cm = 10/100 = 0.1 m

Area of floor = 14 * 12 m^2

Area of tile = 0.1 * 0.1 m^2

No. of tiles required = (14 * 12) / (0.1 * 0.1)

16800

Answer 2

Answer:

16,800 tiles

Step-by-step explanation:

length of hall = 14 m

breadth of hall = 12 m

area of floor = l*b = 14*12 = 1400*1200 = 1680000 cm  sq.

area of 1 tile = s*s = 10*10 = 100 cm sq.

no. of tiles = 1680000/100 = 16,800 tiles
