Answer: (D)

To convert square inches to square feet, you need to know the relationship between these two units of measurement. One square foot is equal to 144 square inches, since there are 12 inches in a foot, and when you square that (12 inches × 12 inches), you get 144 square inches per square foot.

To find out how many square feet are in 1584 square inches, you divide the total number of square inches by the number of square inches in one square foot:

1584 square inches ÷ 144 square inches/square foot = 11 square feet.

Thus, the correct answer of 11 square feet is derived from this division, accurately showing how many square feet are contained within the 1584 square inches. This calculation emphasizes the importance of understanding unit conversions in construction and related fields, ensuring measurements are effectively communicated and utilized.
