The correct answer is:  [C]:  " 40 cm " .
_________________________________________________________
Explanation:
_________________________________________________________

200 feet :  1 cm :: 5 feet: 1 cm; 

200:1 :: 5:1  ;
________________________________________________________
 
5/1 = 200/ x ; 

5x = 200 * 1 ; 

5x = 200 ; 

Divide each side of the equation by "5" ; 
  to isolate "x" on one side of the equation; & to solve for "x" ; 
________________________________________________________
5x / 5 = 200 / 5 ;

x = 40 .

The correct answer is:  [C]:  " 40 cm " .

you have the actual length, 200 ft, and you have to find the model length, x. the ratio is 5:1. you put length over ratio. it becomes 200/5 = x/1. x/1= x. 200/5= x. then do 200/5, which is 40. x, or the length of the model, is 40 ft. hope i helped.
