In a matrix A =


(i) The order of the matrix,


(ii) The number of elements,


(iii) Write the elements a13, a21, a33, a24, a23.

(i) In the given matrix, the number of rows is 3 and the number of columns is 4.


Therefore, the order of the matrix is 3 × 4.


(ii) Since, the order of the matrix is 3 × 4, there are 3 × 4 = 12 elements in it.


(iii) a13 = 19, a21 = 35, a33 = -5, a24 = 12, a23 = .
