Step-by-step explanation:
(AUB)={1,2,3,4,6 }
(AUB)nC={1,2,3,4 }
 
        
             
        
        
        
9!/(8!*(9-8)!)=9
or just use a calculator and use the nCr function
        
             
        
        
        
For this one, instead of breaking it down into 3 shapes we can simply subtract the missing square area from the total enclosing area...

120-16
104 cm^2
