Answer:

area of 1 tile=b*h=10*4=40 cm^2

area of 1000 tiles=40*1000=40000cm^2=4000 dm^2

Total cost=9.50*40000

=95*4000=380000$

Step-by-step explanation:

Hi friend!

Answer:

First we will convert the units to one.

1cm = 1/10 dm

b = 10cm
h = 4cm

10cm = 1dm
4cm = 0.4m

Area of whole room = no. of tiles × area of each tile
= n × (b × h)

(Area of each tile = b × h)
(n = Total no. of tiles)

= 1000 × 1 = 0.4
= 1000 × 0.4
= 400dm²

Cost of polishing 1dm² = $9.50
Cost of polishing 400dm² = $9.50 × 400 = $3800

Therefore, the cost of polishing the tiles in the room = $3800 (₹273296).
