Let's add these lengths together. First lets add the feet -- 4 + 11 + 9 = 24 feet.
Now add the inches. 8 + 7 + 3 = 18
So -- we need 24 feet plus 18 inches.
Since 18 inches is more than a foot, you'll need to convert your answer to get feet plus the number of inches (under 1 foot).
If you post your answer, we'll check it for you.
