Question

If a matrix has $13$ elements, then the possible dimensions (orders) of the matrix are

• A. $1\times 13$ or $13\times 1$
• B. $1\times 26$ or $26\times 1$
• C. $2\times 13$ or $13\times 2$
• D. $13\times 13$

Answer 1

The correct option is A $1\times 13$ or $13\times 1$

AS WE KNOW THAT THE NUMBER OF ELEMENTS IN A MATRIX ARE EQUAL TO THE PRODUCT OF THE (NUMBER OF ROWS & NUMBER OF COLUMNS). THEREFORE 13 COULD ONLY BE FACTORIZED AS (13X1) OR (1X13).
