If the matrix is a square matrix and it contains 36 elements, then the order of the matrix is
Identify the correct statements:
(i) A matrix with 3 columns and 2 rows is of order 3×2. (ii) A matrix with 5 columns and 8 rows is of order 8×5 (iii) If the order of a matrix is 4×3, then it has 12 elements. (iv) If the order of a matrix is 5×3, then it has 10 elements.
If A is a square matrix ⎡⎢⎣123456789⎤⎥⎦ then A+AT is a symmetric matrix.
