Options

• Unit matrix

• Rectangular matrix

• Square matrix

• None of these

Answer 1

Rectangular matrix

Explanation:

A square matrix is one in which the number of rows is equal to the number of columns. Thus, if m = n, an m × n matrix is said to be a square matrix and is known as a square matrix of order 'n'.

For example, A = `[(3, -1, 0),(3/2, 3sqrt(2), 1),(4, 3, -1)]` is a square matrix of order 3.

In general, A = `[a_ÿ]_(m xx m)` is a square matrix of order m.
