100 tiles

Step-by-step explanation:

Area of classroom = length × width = 20 × 30 = 600 ft2

Before we get the area of each tile, convert the dimensions to feet as already stated

Since 1 foot = 12 inches, 36 inches = 3 feet and 24 inches = 2 feet

Area of each tile = length × width = 2 × 3 = 6 ft2 If one tile takes 6 ft2, it takes 100 tiles to cover 600 ft2 (6 × 100 = 600)

Step-by-step explanation:

1 foot =12 inches

Area of the floor = 120×360 inches

= 4320 inches

Area of one tile= 24×36 inches

=864

No. of tiles = 4320/864

=5 tiles. ans
