Transpose Size

Consider a 2 x 9 matrix. What is the new matrix size if it were transposed?

Expand Hint
$$$A=\begin{bmatrix}A & B & C\\ D & E & F\end{bmatrix}$$$
$$$A^T=\begin{bmatrix}A & D\\ B & E\\ C & F\end{bmatrix}$$$
Hint 2
Rows become columns and columns become rows.
When transposing a matrix, the rows become columns, and the columns become rows.
$$$A=\begin{bmatrix}A & B & C\\ D & E & F\end{bmatrix}$$$
$$$A^T=\begin{bmatrix}A & D\\ B & E\\ C & F\end{bmatrix}$$$
Thus, a 2 x 9 matrix will turn into a 9 x 2 matrix.
9 x 2
