How is the rentable area calculated for an office space that requires 8,000 square feet of usable area with a rentable-usable ratio of 1.25?

  1. Rentable area is 10,000 sqft

  2. Rentable area is 12,000 sqft

  3. Rentable area is 16,000 sqft

  4. Rentable area is 8,500 sqft

The correct answer is: Rentable area is 10,000 sqft

To determine the rentable area for the office space, you start with the usable area, which is provided as 8,000 square feet, and then apply the rentable-usable ratio of 1.25. The rentable area is computed by multiplying the usable area by the rentable-usable ratio. In this case, the calculation would be as follows: Rentable Area = Usable Area × Rentable-Usable Ratio So, Rentable Area = 8,000 sqft × 1.25 = 10,000 sqft This calculation reflects the additional space that is typically included in the rentable area, such as common areas and building services that tenants share, which are accounted for in the rentable-usable ratio. By understanding how these areas are calculated, one can precisely determine how much space is required for rental agreements and budgeting in office leasing scenarios.
