I don't see the actual lengths — the problem statement has blanks. Could you tell me the three lengths (in feet)?

If you prefer a general answer: if the lengths are a, b, and c feet, the total required is a + b + c feet. For example, if they were 4 ft, 7 ft, and 9 ft, the total would be 4 + 7 + 9 = 20 feet.
