Answer:
Elias would be correct.
Explanation:
Elias is correct because the length must be GREATER than 4 inches and less than 16. Elias is right, assuming we take “between 4 inches and 16 inches" to be not inclusive. With a length of either 4 (=10-6) or 16 (=10+6), we would have not a triangle, but a straight line. Therefore, Elias is correct.
