Final answer:
To estimate the fishpond's size, divide the distance around the pond by 4 to get an approximate length for each side of the rectangle.
Step-by-step explanation:
To estimate the size of the fishpond, we can consider the distance around the pond as the perimeter of a rectangle. Since the distance around the fishpond is 24 yards, we can assume the rectangle has sides of equal lengths. Therefore, by dividing the perimeter by 4, we can estimate that each side of the rectangle is approximately 6 yards.
