Answer: Yes
Explanation:
To determine whether three lengths can form a triangle, we need to check if the sum of the two smaller lengths is greater than the largest length.
Let's order the given lengths from smallest to largest:
14yd, 19yd, 31yd
Now, we can check if the sum of the two smaller lengths (14yd and 19yd) is greater than the largest length (31yd):
14yd + 19yd = 33yd
Since 33yd is greater than 31yd, we know that the three lengths can form a triangle.
Therefore, the answer is yes, 31yd, 14yd, and 19yd can form a triangle.
