Let $a$ and $b$ represent the lengths of the legs of a right triangle, and $c$ represent the length of the hypotenuse. Find $b$ if $a = 6$ meters and $c = 12$ meters.

Express your answer in simplest radical form $b = A \sqrt{C}$, where $A$ and $C$ are all integers.

Answer (in meters): $A =$ and $C =$
