Find the area of the ceiling by multiplying the length by the width. $24 ft \times 26 ft = 624 sq\ ft$ Find the area that each tile will cover by multiplying the length by the width. $2 ft \times 4 ft = 8 sq\ ft$ Divide to find the number of tiles required. $624 \div 8 = 78 \ tiles$ Note: To avoid waste, the tiles need to be arranged such that the 4 ft side of the tile aligns with the 24 ft side of the ceiling.
