Question

Which matrix can be a rectangular matrix?

Answer 1

$\huge{\mathcal{\blue{Answer}}}$

Also, any matrix with 3 rows and 3 columns will also be a square matrix. But if the matrix has 2 rows and 3 columns, it will not be a square matrix anymore. Then it's a rectangular matrix. This means a matrix with an unequal number of rows and columns is a rectangular matrix.
