Well from what im gathering from your broken english and this ridiculously worded problem, here is how i see it.
15+2x=33
33-15=18, 18/2=9, 15+2(9)=33, 15+18=33, 33=33
x=9
 
        
             
        
        
        
Answer:
88 cm²
Step-by-step explanation:
The perimeter of each square is 22 cm 
we should divide by 4 to get the length of the square 
22/4=5.5 cm
so we should multiply by 2 to get the length of the rectangle 
5.5*2= 11 
the perimeter is : 
P= 5.5+5.5+5.5+11+11+5.5+5.5+11+11+5.5+5.5+5.5 =  88 cm²
