If `A` is `2 times 3` matrix and `B` is a matrix such that `A^T\ B` and `B A^T` both are defined, then what is the order of `B` ?

Text Solution

Verified by Experts

Given that,
`A` is `2 times 3`

`A^T\ B` and `B A^T` both are defined

`A^T` will be order of `3 times 2`

`A^T B` is defined, then row will be `2`
