Question

2 3 of a matrix the order - li is => 5 > 4​

Answer 1

Answer:

5×4

Order of matrix A=4×3(Given)

∴ Order of matrix A

′

=3×4

Order of matrix B=3×5(Given)

∴ Order of matrix B

′

=5×3

Number of rows in A

′

is equal to the number of columns in B

′

, i.e., 3

Therefore,

[B

′

]

5×3

×[A

′

]

3×4

=[AB]

5×4

Hence the order of matrix B
