10.2+10.2*20/100= 12.24 inches
                                
             
                    
              
              
                
                
Basically, to answer this question, you have to increase 10.2 by 20%.hence,
10.2×20= 204
204÷100= 2.04
10.2+2.04= 12.24
answer- 12.24inches
