Answer:
504 RS
Step-by-step explanation:
length of room = 5.6 metre
breadth of room = 3.6 metre.
area of room = L * B
= 5.6 * 3.6
= 20.16 ^ 2
side of the square tiles = 10cm = 0.1m
area of the = 0.1*10.1 = 0.01M^2
tiles required = 20.16/0.01 = 20.16*100
= 2016
rate of laying tiles = 5 Rs for 2 tiles
= 2.5 / tiles
=cost of laying tiles in the room=
= 2016*25/10
= 2016*5/2
= 1008 * 5
= 5040 RS.
