Explanation:

Step1: Calculate classroom area

The classroom is a rectangle, so area = length × width. Length = 20 ft, width = 15 ft. So area = \( 20 \times 15 = 300 \) square feet.

Step2: Calculate number of tiles

Each tile has area 4 square feet. Number of tiles = total area ÷ tile area = \( \frac{300}{4} = 75 \).

Answer:

B. 75 tiles
