Question

find the cost of flooring a square room of side 10 m with marbles tiles 25cm ×20cm at the rate ​

Answer 1

Answer:

Total cost is Rs 15000.

Step-by-step explanation:

The cost of flooring a square room of side 10m with marble tiles 25cm ×20cm at the rate of ₹ 7.50 per tile is Rs 15000.

Area of a square = Side × Side

If side = 10m, then the area of the square room is

Area =  (10 × 10) m^2 = 100m^2

For 1 tile,

Length = 25cm = 0.25m

Breadth = 20cm = 0.20m

Area of 1 tile = length × breadth = (0.25 × 0.20)m^2 = 0.05m^2

So, the number of tiles fitted in room = (Area of room/Area of 1 tile)

= (100/0.05) = 2000

So, 2000 tiles can be fitted.

Given, per tile costs Rs 7.50

So, cost of 2000 tiles = Rs (2000 × 7.50) = Rs 15000

So, total cost is Rs 15000.  (Ans)
