B Correct answer
Explanation

Total floor area = 50 * 40 = 2000 sq ft. Each table is 4 * 4 = 16 sq ft. 25 tables = 25 * 16 = 400 sq ft. Percent area = (400 / 2000) * 100 = 20%.

AI explanation

First, calculate the total floor area of the auditorium using the length and breadth formula, which gives 50 feet times 40 feet equal to 2000 square feet. Next, find the area of one table, which is 4 feet times 4 feet equal to 16 square feet. Since there are 25 tables placed side by side, the total area covered by the tables is 25 times 16, resulting in 400 square feet. To find the percentage, divide the area of the tables by the total floor area and multiply by 100, yielding (400 / 2000) * 100 = 20 percent.
