Question

what is the number of rectangular tiles of size 10cm×8cm needed to cover the floor of a room of size 12cm ×10cm​

Answer 1

Answer:

15000 slabs are required to cover the floor of the hall.

Step-by-step explanation:

Measurements of the floor :

Length= 12 m = 1200 cm

Breadth= 10m = 1000 cm

So area of the floor = length × breadth

= 1200000 cm^2.

Measurements of the rectangular slabs:

Length= 10cm

Breadth = 8 cm

Therefore, area of each slab = 10×8 = 80cm^2

So the number of slabs required to cover the floor = Area of the floor/Area of each slab

= 1200000/80 = 15000 slabs.

Answer 2

Answer:

Area of rectangle floor = 12 x 10 = 120

Area of rectangle tile = 10 x 8 = 80

No.of tiles required = 120/80 = 1.5 tiles
