[Answered] Which of the following statements are true about scalar multiplication of matrices? You can multiply a matrix of any size by a scalar. For any matrix [tex]$A, 1 \times A=A$[/tex]. For any scalar [tex]$r, r l=l$[/tex], where [tex]$l$[/tex] is the identity matrix. You can scale geometric figures using scalar multiplication. Scalar multiplication is a shortcut for repeated addition of the same matrix. Scalar multiplication is not possible for matrices that are not square.
