If a matrix h as 28 elements, what are the possible orders it can have?

Text Solution

Verified by Experts

We know that, if a matrix is of order `mx x n` it has mn elements, where m and n are natural numbers.
We have , `mxxn=28`
`rArr (m,n)={(1,2 8),(2,14),(4,7),(7,4)7,4),(14,2),(28,1)}`
So, the possible orders are `1xx28,2xx14,4xx7.7xx4,14xx2,28xx1`
Also, if has 13 elements then `mxxn=13`
`rArr (m,n)={(1,13),(13,1)}`
Hence, the possible orders are `1xx13,13xx1`
