The answer is:  [A]:  " 120 ft² " .
_______________________________________________________
Explanation:
_______________________________________________________
Set up a ratio as a fraction:
_______________________________________________________

       8/3 = 320/x ;
_______________________________________________________
Cross-multiply:
_____________________________________________________

8x = 3 * 320  ;

8x = 960 ;

Divide each side of the equation by "8" ;
 to isolate "x" on one side of the equation ; and to solve for "x" ;
______________________________________________________
   8x / 8  =  960 / 8 ;

to get:  x = 120 .

The answer is:  [A]:  " 120 ft² " .

Any questions? Hope this helps!
