Q5 of 54 Page 124

Matrix consists of 30 elements. What are the possible orders it can have?

Since there are 30 elements, we can make the multiples of 30, which are:- 1×30; 30×1; 2×15; 15×2; 3×10; 10×3; 5×6 and 6×5


Therefore, the possible orders of a matrix are 1×30; 30×1; 2×15; 15×2; 3×10; 10×3; 5×6 and 6×5
