Why might a person make a garden with the least perimeter?

A person might make a garden with the least perimeter to maximize the area available for planting while minimizing the amount of Fencing or materials needed for boundaries. This can be a cost-effective approach, as it reduces the amount of resources required for enclosing the garden. Additionally, a garden with a smaller perimeter may be easier to maintain and manage, as there is less space for weeds to encroach and pests to enter.
