Answer 1

Answer:

1000 tiles; Rs. 20,000

Step-by-step explanation:

Area of tiles = 12cm*10cm = 120cm^2

Area of wall = 3m*4m = 300cm*400cm = 120000cm^2

No. of tiles = Area of wall / Area of tiles

                  = 120000 / 120 = 1000 tiles.

-->Total Cost = 1000 tiles * Rs.20 per tile = Rs. 20,000.
