Final answer:
The area of a 48 inch x 60 inch rectangle is 20 square feet.
Step-by-step explanation:
To find the area of a rectangle in square feet, we need to multiply the length and width of the rectangle in feet. The given dimensions are 48 inches and 60 inches. We can convert these measurements to feet by dividing each measurement by 12 since there are 12 inches in a foot. So, 48 inches is equal to 4 feet and 60 inches is equal to 5 feet. Now we can find the area by multiplying 4 feet and 5 feet, which gives us 20 square feet.
