Answer 1

Answer:

Tiles required will be 100 and Cost of all tiles = Rs. 25000

-----------------------------------------------------------

Step by step explanation:

Important units for the question :-

1 m = 100 cm

Now,

Measurements -

Area of Tile = (100×12)cm = 1200 cm²

Area of Wall = (3×4)m = (300×400)cm = 120000 cm²

Now,

Tiles required = Area of wall/Area of each tile

= 120000/1200

= 100 tiles

Cost of 1 tile = Rs. 250

Now, Cost of 100 tiles = 250×100 = Rs.25000
