Answer 2

Length of the room = 5.6m
Breadth of the room= 3.6m
Area of the room = L x B
                             = 5.6 x 3.6 = 20.16m^2
Side of the square tile = 10cm = 0.1m
Area of the tile = 0.1 x 0.1 = 0.01m^2
Tiles required = 20.16/0.01 = 20.16 x 100 = 2016
Rate of laying tiles = 5rs for 2 tiles = 2.5Rs/tile
Cost of laying tiles in the room = 2016 x 2.5
= 2016 x 25/10
= 2016 x 5/2
= 1008 x 5
= 5040RS
