Vedclass · Answer

(C) square matrix is defined as a matrix in which the number of rows is equal to the number of columns $(m = n)$.$(a)$ $[1]$ is a $1 	imes 1$ matrix,which is a square matrix.$(b)$ $\begin{bmatrix} 2 & 2 \ 2 & 2 \end{bmatrix}$ is a $2 	imes 2$ matrix,which is a square matrix.$(c)$ $\begin{bmatrix} 3 & 3 & 3 \end{bmatrix}$ is a $1 	imes 3$ matrix. Since the number of rows $(1)$ is not equal to the number of columns $(3)$,it is not a square matrix.$(d)$ $\begin{bmatrix} 1 & 1 & 1 \ 1 & 1 & 1 \ 1 & 1 & 1 \end{bmatrix}$ is a $3 	imes 3$ matrix,which is a square matrix.Therefore,the correct option is $(c)$.
