A room is 45 m x 15 m. What is the least number of rectangle tiles required to pave the floor of the room, if each tile is 50 cm x 1m?
Hey Batala426, If the room is 45m x 15m, then the total area is 675 metres squared. Each tile is 50cm x 1m, so the area of each one is 0.5 metres squared. 675 / 0.5 = 1350 So the least number of tiles you need to pave the whole room is 1350 tiles. Hope this helps! Chen :D
