Answer:
The  square feet of space per employee is more in building B . 
Step-by-step explanation:
Given as :
The office space of building A = 7,500 ft²
The number of employee in building A = 320
Let The space in building A per square feet per employee = x ft²
So,  x = 
I.e x = 
∴   x = 23.43 per square feet per employee 
<u>So, For building A  23.43 per square feet per employee </u>
Again , 
The office space of building B = 9,500 ft²
The number of employee in building B = 317
Let The space in building B per square feet per employee = y ft²
So,  y = 
I.e y = 
∴   y = 29.96 per square feet per employee 
<u>So, For building B 29.96 per square feet per employee </u>
So , from calculation it is clear that the square feet of space per employee is more in building B .
Hence The  square feet of space per employee is more in building B .  Answer
