Answer:  Option 'C' is correct.
Step-by-step explanation:
Since we have given that 
Polygon X is similar to polygon.
And Polygon X is three times the size of polygon Y.
So, it becomes,

Hence, perimeter of polygon Y is 27.
Therefore, Option 'C' is correct.
 
        
                    
             
        
        
        
65 million plus 4000 = <span>sixty-five million four thousand</span>
        
                    
             
        
        
        
F(n) = 75*1/5n
This is because the base value would be 75 and it is divided by 5 each part of the sequence. 
        
             
        
        
        
Answer: Parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel.
