Verified Answer :

24 feet = 288 inches. 
9.96*9.96 = 99.2016
288 ÷ 99.2016 ≈ 3

hope this helps! :)

Area of the tile = 9.96 inches 9.96 inches = 99.2016 square inches.

Area of tile = 99.2016
inches inches

Area of the floor = 24 square feet.

Number of tiles = Area of floor / Area of 1 tile

24 square feet = 24
1 feet 1 feet               But  1 feet = 12 inches.

Area of floor = 24
12 inches 12 inches


Number of tiles = (24
12 inches 12 inches) / (99.2016inches * inches)

                         ≈ 34.84

We need  to round up the number of tiles to 35

Number of tiles = 35

Hope this explains.
