# Use the following matrices for Problems 1-28. A = [ 1 0 − 2 3 2 1 4 0 3 ]             B = [ 1 1 3 0 4 2 1 1 3 2 0 1 ]             C = [ 5 3 1 2 ] D = [ 4 2 3 5 ]             E = [ 1 0 4 5 1 0 ]             F = [ 1 2 3 − 1 0 1 2 − 3 − 4 ] G = [ 2 1 1 1 0 4 5 1 0 ]               Z = [ 0 0 0 0 0 0 0 0 0 ] Which of these matrices are square?

To determine

Square matrices from the given matrices.

Explanation

Given information:

A=[10âˆ’2321403]â€‰â€‰â€‰â€‰â€‰â€‰B=[113042113201]â€‰â€‰â€‰â€‰â€‰â€‰C=[5312]

D=[4235]â€‰â€‰â€‰â€‰â€‰â€‰E=[104510]â€‰â€‰â€‰â€‰â€‰â€‰F=[123âˆ’1012âˆ’3âˆ’4]

G=[211104510]â€‰â€‰â€‰â€‰â€‰â€‰â€‰Z=[000000000]

Calculation:

A matrix is called a square matrix if the number of rows of the matrix equals the number of columns.

Matrix A=[10âˆ’2321403].

This matrix has 3 rows and 3 columns.

Therefore, matrix A is a square matrix.

Matrix B=[113042113201]
