In the figure above, what is the length of AC ?

1. x + y = 13

2. xy=36

1. AC= 2(x+y) =2*13 = 26 Suff
2. If xy=36, x,y have diff possible pair if they are strictly integers e.g., (1,36),(2,18) etc ..... if we consider non-integers there will be more e.g., $$(\frac{36}{7} , 7)$$, $$(\frac{36}{11},11)$$.... etc..... so x+y will be having varied results for each pair. --Not Suff .......................Thus Ans A
