When measuring the amount of fabric to use for a pond, you should take the maximum length times?

Explanation:
When lining a pond, you need material that can cover the bottom along the long dimension and come up the sides on both ends. The width of the liner should account for height on both sides, which is 2 × depth, and you also want some extra for overlap and securing the seam. Adding 3 feet gives enough material to wrap the liner up the sides and have a comfortable seam allowance. So the amount of fabric you need is the maximum length of the pond times (2 × depth + 3 ft). The other options don’t provide enough material for both sides or for seam allowance, so they can lead to not having enough liner.
