The correct basis for determining the amount of welded wire reinforcement required is related to area. When calculating the necessary reinforcement, it's important to consider the surface area that the welded wire will cover. This is critical because the reinforcement must provide adequate support for the specific load requirements of the concrete structure. The area dictates how much reinforcement is needed to effectively distribute loads and prevent cracking or structural failure.

In this context, while weight, thickness, and shape all play roles in the broader aspects of design and material selection, the fundamental requirement for welded wire reinforcement focuses on the surface area to ensure that the concrete has sufficient tensile strength and stability under load. The area allows for a precise calculation of the number of wire mesh sheets or mats necessary for optimal performance.

Understanding the relationship between area and reinforcement helps in making informed decisions about the overall structural integrity and compliance with relevant building codes and design standards.
