How is total office area calculated when there are 5 offices?

Total office area is determined by calculating the area allocated for each office and then multiplying that figure by the number of offices. In this case, if each office has a designated area of 120 square feet, you would multiply that by the number of offices, which is five. Therefore, the total office area is calculated as ( 120 , \text{sf} \times 5 = 600 , \text{sf} ).

This method of calculation is standard in architectural practice, as it quantitatively reflects the total space needed for the specified number of offices. Understanding how to apply such area calculations is fundamental in design and space planning, ensuring that adequate space is assigned based on the intended use of each office. The choice of 120 square feet suggests that this is the planned or agreed-upon size for each office, making it the correct basis for this calculation.
