A Correct answer
Explanation

Area of floor = 300 * 200 = 60000. Area of carpet = 180 * 180 = 32400. Uncarpeted area = 60000 - 32400 = 27600.

AI explanation

Using the area of a rectangle formula, the total floor area is 300 m multiplied by 200 m, giving 60000 sq m. Using the area of a square formula, the carpeted area is 180 m squared, resulting in 32400 sq m. Subtracting the carpeted area from the total area gives 60000 minus 32400, resulting in 27600 sq m.
