Question

Find the cost of tiling the floor of a room with side 15m at the

rate Rs.20 per square metre​

Answer 1

Assuming the room is square (as only one side is mentioned)

Cost of tiling = 20 × Area of surface

Area of surface = 15 × 15 (area of the square surface)

= 225m^2

Cost of tiling = 225×20

= Rs.450

Thank you
