    Step-by-step explanation:

    Area of floor = (41/2) * (67/4) = 2747/8 ft²

    Area of a tile = (1/2)(1/4) = 1/8 ft²

    Number of tiles required = Area of floor / Area of a tile

    = (2747/8)/(1/8)

    = 2747

    Cost of 1 tile = rs 62

    Cost of 2747 = 2747 * 62 = rs 170314

    Total cost of tiling the border of the room by the designer tiles. = rs 170314
