Answer
78 tiles
Work Step by Step
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.
