Answer 1

Hey mate..

Here is your answer ₹4888

Dimension of room = 6.5 * 5

Now,

Area of floor = 6.5*5

=32.5m^2

Area of square tile having side 25cm

Area = 0.25*0.25.(in metre)

=0.0625m^2

No of tiles required = 32.5/0.0625
=520 tiles

Rate of flooring = 9.40 rupee /tiles

Cost of flooring = 540 * 9.40

=4888 rupee..

Hope it helps
