If A is a square matrix of order 3 and |A | = 4 find the value of |2A |.

As per the question statement, order of the square matrix A is 3 and |A | = 4.

To find the value of |2A |, take the cube of 2.

|2A | = ( 2)³ X |A |

Now, substituting |A | = 4,

|2A | = 8 X 4

= 32

Hence, the value of |2A | is 32.
