If A is 3 x 4 matrix, then the order of the matrix B such that ABT and
BAT are square matrices, then order of the matrix B is
(a). 3x3
(b). 4x4
(c). 3x4
(d). 4x3.​

Answer 1

Answer:

Option d)

Step-by-step explanation:

Given: A is 3*4

ABT and BAT are square matrices

Let B = m*n

ABT = (3*4)(m*n)(T)

By product rule m=4

since it is square matrix n=3

Similarly it applies for BAT

Therefore order of B is 4*3
