Final answer:
To find the total square footage of the building, divide the leased space (2,500 square feet) by the percentage of space it represents (12.5%), resulting in a total of 20,000 square feet. The correct option is a.
Step-by-step explanation:
The question asks to determine the total square footage of an office building if a doctor's office, which occupies 2,500 square feet, represents 12.5% of the total space. To find the answer, we can set up a proportion where 2,500 square feet is 12.5% of the total space (let's call it T). The proportion will then be 2,500 = 0.125 T.
We can find T by dividing both sides of the equation by 0.125: T = 2,500 / 0.125 = 20,000 square feet.
Therefore, the total square footage of the building is 20,000 square feet, which makes option a (20,000) the correct answer.
