Answer:
4 1/3 inches   Smaller piece
16 2/3 inches   Larger piece
Step-by-step explanation:
x + (2x + 8) = 21
3x + 8 = 21
3x = 13
x = 13/3 
x = 4 1/3 inches   Smaller piece
2x + 8 = 8 2/3 + 8 
2x + 8 = 16 2/3 inches   Larger piece
 
        
             
        
        
        
A= (a+b)/2*h
A=(12+15)/2*5
A=(27/2)*5
A=13.5*5
A=67.5in
        
                    
             
        
        
        
33.33? im not sure, but you do a/b=p/100. p is the percent, a is the part of the whole number, b. so the equation would be 20/b=60/100. then you do cross multiplication (60b=2000) then you divide.
