To find the total floor area \( A \) of all the offices in the building, you can use the equation:
\[ A = n \times a \]
where:
- \( A \) is the total floor area,
- \( n \) is the number of offices, and
- \( a \) is the floor area of each office.
In this scenario:
- \( n = 23 \) (the number of offices),
- \( a = 305 \) square feet (the floor area of each office).
Plugging in the values:
\[ A = 23 \times 305 \]
Calculating this gives:
\[ A = 7015 \text{ square feet} \]
So the total floor area of all the offices is 7015 square feet.
