(i) Row of the given matrix $=3$
Column of the given matrix $=2$
So, order of the given matrix is, $3\times 2$.
Hence, the matrix is a rectangular matrix $=3\times 2$.
(ii)
Row of the given matrix $=1$
Column of the given matrix $=2$
So, order of the given matrix is, $1\times 2$.
Hence, the matrix is a rectangular matrix $=1\times 2$.
