Answer:
I don't really know but one triangle is 180 degrees so two added together is 360 degrees... 
but ohh I remembered
a=c+d (since a+b=180 and c+d+b=180)
e=g+h (since e+f=180 and g+h+f= 180)
and the fact is that c+d+g+h+b+f=the angle sum of quadrilateral PQRS 
 a+e+b+f= the angle sum of quadrilateral PQRS (by substitutions)
 a+e+b+f=360 (four angles are from one origin so it's 360 degrees )
 
        
             
        
        
        
F. 24, this is because if you split the bigger square in half you’ll get 6 and perimeter is the addition of all sides. So 6+6+6+6=24

Answer: 59
Step-by-step explanation:
Given
2b³+5 and b=3 ⇒ 2b³+5=2(3)³+5
Simplify exponents
  2(3)³+5
=2(3×3×3)+5
=2×27+5
Multiplication
=54+5
Addition
=59
