      Question

      In a rectangular floor of length and breadth of 19

      metres and 6 metres, respectively, square tiles each of 2 metre edge length are to be laid. If the cost of each tile is Rs. 150, then find the total cost of the tiles to be laid in the room.
      A Rs. 4205 Correct Answer Incorrect Answer
      B Rs. 4225 Correct Answer Incorrect Answer
      C Rs. 4275 Correct Answer Incorrect Answer
      D Rs. 4285 Correct Answer Incorrect Answer

      Solution

      Area of the rectangular room = 19 ร— 6 = 114 m2 Area of each tile = 2 ร— 2 = 4 m2 So, number of tiles to be laid in the room = (114/4) = 28.5 So, total cost of all the tiles laid in the room = 28.5 ร— 150 = Rs. 4275
