Question

Which of the following is square or rectangle

a)A=[-2 1 0]
0 1 -1
1 -1 3

b) B=[0 -7]
3 8

Answer 1

To determine if a matrix represents a square or rectangle, we need to check its dimensions.

Matrix A is a 3x3 matrix (3 rows and 3 columns), so it is a square matrix.

Matrix B is a 2x2 matrix (2 rows and 2 columns), so it is also a square matrix.

Therefore, both matrices A and B are examples of square matrices.
