Question

A floor is 4.2 m long and 3.5 m wide. A 7 cm square tile costs RS. 13.25. What will be the cost to cover the floor with these tiles?

Answer 1

Answer:

length of the floor = 4.2m

breadth of the floor= 3.5m

Area of the floor =length ×breadth

= 4.2×3.5

=14.7m^2

the floor has to be covered with square tile

length of the tile= 7 cm or 0.07m

area of the tile = side ×side

area = 0.07×0.07

=0.0049 m^2

No.of tiles to cover the floor= 14.7/0.0049

= 3000 tiles

cost of each tile=Rs.13.25

cost of tiles to cover the floor=3000×13.25

Therefore the cost of the tiles to

cover the floor is =Rs.39,750
