Ok, so the diameter of the circles is 6 because is the half of the rectangle,

the radius is half the diameter so is 3

the height of the rectangle is equal to the diameter of the circle so is 6

the shaded area is the total area of ​​the rectangle minus the area of ​​the two circles

then


\begin{gathered} (12*6-2(3^2\pi))cm^2 \\ (72-18\pi)cm^2\approx15.5^{}cm^2 \end{gathered}
