Final answer:
The length of the pond is 32 yards.
Step-by-step explanation:
To find the length of the pond, we can use the fact that the length from point Y to point Z is 15 yd and the length from point X to point Z is 17 yd. Since the pond length is the same from both points Z, we can add these measurements together to find the length of the pond.
Length of the pond = 15 yd + 17 yd = 32 yd
Therefore, the length of the pond is 32 yards.
