In the matrix \( \begin{bmatrix} 2 & 5 & 19 & -7 \\ 35 & -2 & \frac{5}{2} & 12 \\ \sqrt{3}& 1 & -5 & 17 \end{bmatrix}\), write:
(i) The order of the matrix
(ii) The number of elements
(iii) Write the elements a13, a21, a33, a24, a23
Steps:
(i) Since, in the given matrix, the number of rows is 3 and the number of columns is 4,
the order of the matrix is 3 × 4.
(ii) Since the order of the matrix is 3 × 4,
there are 3 × 4 = 12 elements.
(iii) Here,
a13 = 19
a21 = 35
a33 = -5
a24 = 12
a23 = 5/2
