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
