Answer 1

Answer:

1000 tiles

Step-by-step explanation:

l = 5m = 500 cm

b= 4m = 400 cm

Area of a tile = 200 cm²

Area of floor = l×b

= 500 × 400

= 200000 cm²

tiles required = Area of floor/ Area of a tile

= 200000/ 200

= 1000 tiles

1000 tiles will be required to cover the floor.

Hope it helps you

Answer 2

Answer: 1000 tiles

Step-by-step explanation:

Total area of room = number of tiles * area of 1 tile

Let number of tiles= n

Total area of room = l*b

= 5*4

=20 m²

= 200000cm²

Area of one tile=200 cm ²

Number of tiles= Total area of room/ area of one tile

N= 200000/200

N=1000 tiles
