Let the length of shortest side be - x 
length of medium side - x +3 
length of longest side - x +3 + 11 
so , according to question 
=> x + x +3 + x +3 + 11 = 59 
=> x + x +x + 3 + 3 + 11 = 59 
=> 3x = 59 - 17 
=> 3 x = 42 
=> x = 42/3 
=> x = 14 
Shortest side = x = 14 
medium side = x + 3 = 14+3 = 17 
longest side = x + 3 +11 = 14 + 3 + 11 = 28

Answer:
13
Step-by-step explanation:
Draw a picture!
You have a right triangle with legs of 5 and 12. 
By the Pythagorean Theorem, the hypotenuse is √(5²+12²) = 13
 
        
             
        
        
        
2=6
4=8
6=10
8=12
I added +4 for each
