Question
In a rectangular floor of length and breadth of 20
metres and 10 metres, respectively, square tiles each of 2 metre edge length are to be laid. If the cost of each tile is Rs. 189, then find the total cost of the tiles to be laid in the room.Solution
Area of the rectangular room = 20 Γ 10 = 200 m2 Area of each tile = 2 Γ 2 = 4 m2 So, number of tiles to be laid in the room = (200/4) = 50 So, total cost of all the tiles laid in the room = 50 Γ 189 = Rs. 9450
