Question

a tile measure 10 cm × 15 cm . how many such tiles are required to cover a floor of 5m × 3.5 m​

Answer 1

Answer:

Rs. 2000

Step-by-step explanation:

Given area of the wall = 3 m x 4 m = 12 m2

Also given that area of one marble tile = 10 cm x 12 cm = 120 cm2  = 0.012 m2

[Since 1 m2 = 10000 c m2] Number of tiles required to cover the wall = Area of wall/ Area of one marble tile = 12/0.012 = 1000 tiles Cost of one tile = Rs. 2 Total cost = Number of tiles x Cost of one tile = Rs. (1000 x 2) = Rs. 2000.
