If b was 3 a will be 6 because 2*3=6
and for the second part b will be 3.5 because 2*3.5=7
        
                    
             
        
        
        
Answer:
33(5/6) sq miles
Step-by-step explanation:
Area = LxW
812 = 24xW
Divide by 24
W = 33.8333333 ( 33 (5/6)
8 is non repeating
3 is repeating
 For nominator subtract the non repeating    (83-8 = 75)
For  denominator :  one 9 for each non repeating,one zero for each repeating (only 3 is repeating,then one zero) 
   75/90  = 5/6
