A rectangular tile having a perimeter of 224 cm has been used to pave a floor of length and breadth 25.6 m and 14.4 m, respectively. If the ratio of length to breadth of each tile is 4:3, then find the number of tiles required to pave the floor completely.

  1. 1200

  2. 1050

  3. 1140

  4. 1540

Answer: A

Solution

Let the tile dimensions be 4x and 3x. Then 2(4x + 3x) = 224, so x = 16 cm. Tile dimensions are 64 cm × 48 cm. Number of tiles = (2560 × 1440)/(64 × 48) = 1200.
