Final answer:
To find the area in square feet, convert the measurements from inches to feet. The correct answer is 20 square feet.
Step-by-step explanation:
To find the area in square feet, you need to convert the measurements from inches to feet. Since there are 12 inches in a foot, divide 48 inches by 12 to get 4 feet. Similarly, divide 60 inches by 12 to get 5 feet. Next, multiply the two measurements together: 4 feet x 5 feet = 20 square feet.
