विकल्प

• 1 × 1

• 1 × 2

• 2 × 1

• 2 × 2

Answer 1

If `[(1, 3),(2, -5)], B = [(2),(-3)]` then the order of matrix B is 2 × 1.

Explanation:

Count rows and columns in matrix B

B = `[(2),(-3)]`

There are 2 rows (each number is on a new line)

There is 1 column

So, the order of matrix B is 2 × 1.
