We are given x < 3 and y < 2 ; no lower bound specified for either of the variables.
x and y could
be x=-3 and y=-2 we get xy=6 or they could be very small negative numbers then xy would be much greater than 6.
On the other hand x=1 y=1 which results in xy=1 which is smaller than 6 so Statement (1) is not sufficient
y^2 < 64 can be rewritten as -8< y <8 ,
Since x is positive, we can test the extremes without worrying about changing the direction of the inequality sign
-8*(2/3) < xy < 8*(2/3)
-5.3333 < xy < 5.333
So we can answer the question "Is xy<6" with the Statement (2) ALONE.
Kudos (+1) if you find this post helpful.
