You can split the combined shape into separate shapes and find the area of each of those. once you have done that add all of the areas together and that will get you your combined shapes area.
        
             
        
        
        
Let us say that:
K = age of Kristen
B = age of Ben
 
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
 
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
 
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
 
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
 
So Kristen is 20 while Ben is 12.
