What is the area of a window that is 36" wide by 48" tall?

• A. 10 ft²
• B. 12 ft²
• C. 15 ft²
• D. 8 ft²

Answer: (B)

To determine the area of a window that is 36 inches wide and 48 inches tall, the area can be calculated using the formula for the area of a rectangle, which is width multiplied by height. In this case, the width is 36 inches and the height is 48 inches. First, multiply the two dimensions together: 36 inches * 48 inches = 1728 square inches. To convert square inches to square feet, you divide by the number of square inches in a square foot, which is 144 (since there are 12 inches in a foot, and 12 inches * 12 inches = 144 square inches). Thus: 1728 square inches ÷ 144 square inches per square foot = 12 square feet. Therefore, the area of the window is 12 square feet. This corresponds with the choice indicating an area of 12 ft².
