Convert the feet to inches first. 2 ft = 24 inches. We must divide this total length by the length of each tile to determine how many tiles will fit across the tabletop:
24 ÷ (1/4) = (24/1) ÷ (1/4) = (24/1) × (4/1) = 96/1 = 96
96 tiles will fit across the tabletop.
Since the tabletop is as long as it is wide, that means we will have 96 rows of 96 tiles:
96(96) = 9,216 tiles to cover the tabletop.
