Find \(\frac{K \cdot (-L)}2\), if:
\[
K=\left (\array{
3& 0 & 1\cr
2 & 3 & 4 \cr
1& -1 & 1} \right ),~
L=\left (\array{
2& 3 & 0\cr
1 & 1 & -1 \cr
2 &0& 1 } \right )
\]
\(
\left (\array{
-4& -4.5 & -0.5\cr
-7.5 & -4.5& -0.5\cr
-1.5 & -1& -1 } \right )
\)
\(
\left (\array{
-4& 4.5 & 0.5\cr
-7.5 & -4.5& -0.5\cr
-1.5 & -1& -1 } \right )
\)
\(
\left (\array{
-4& -4.5 & -0.5\cr
7.5 & -4.5& -0.5\cr
-1.5 & -1& -1 } \right )
\)
\(
\left (\array{
-4& -4.5 & -0.5\cr
-7.5 & 4.5& -0.5\cr
-1.5 & -1& 1 } \right )
\)
