The option that addresses detailed information about the size of seating areas is the AV room layout drawings. These drawings are specifically designed to illustrate the arrangement of audio-visual equipment and the seating layout within a room. They provide a comprehensive view of how the space is utilized, including the dimensions of seating areas, ensuring that the placement of seats is optimized for viewing and sound experience.

While equipment rack drawings focus primarily on the organization and configuration of equipment, as-built drawings document the final state of a project after construction, showing what was actually built compared to the original plan. Change orders are modifications to a contract and do not typically provide the specific spatial details necessary for determining the sizes of seating areas. Therefore, AV room layout drawings are essential in ensuring that the design meets aesthetic and functional requirements for seating arrangements.
