Answer:
   10)  C 4/9
   11)  B 24
Step-by-step explanation:
10) The area ratio is the square of the ratio of side lengths. The ratio of side lengths is ...
   RS/LM = 6/9 = 2/3
Then the area ratio is ...
   (2/3)² = 4/9
__
11) Using the result of question 10, the area of ∆RST is ...
   (4/9)(54 in²) = 24 in²
 
        
             
        
        
        
So, what you would have to do is figure out how old he is not which is 30 yrs old because it is half of 60.
So, after this you would have to find a number that would go into 60 four times which is 15.
So, your answer would be 15. 
HOPES THIS HELPS!!!!
