Question

In the matrix , write:

(i) The order of the matrix
(ii) The number of elements,
(iii) Write the elements a₁₃, a₂₁, a₃₃, a₂₄, a₂₃

Answer 1

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

(iii) a₁₃ = 19, a₂₁ = 35, a₃₃ = −5, a₂₄ = 12, a₂₃ = 5/2
