Question

Find the cost of flooring a room 6.5 m by 5 m with square tiles of side 25 cm at the rate of Rs 9.40 per tile .

Answer 1

Number of tiles needed across length of room
= 6.5m / 25cm
= 650cm / 25cm
= 26 tiles

Number of tiles needed across breadth of room
= 5m / 25cm
= 500cm / 25cm
= 20 tiles

Total number of tiles needed
= 26 * 20
= 520 tiles

Cost of flooring the room
= Rs9.40 * 520
= RS 4888
