If A and B are both square matrices of order 2 x 2 and C is a matrices with 5 columns then what should be order of D such that CD = A
2 x 2
2 x 5
5 x 2
5 x 5
As we have learned
Square Matrix -
Number of rows Number of columns
- wherein
A matrix Where
is of order 2*2
Thus
Thus a = 2 ;
and D has order 5 x 2
in order to get a square matrix
Option 1)
2 x 2
Option 2)
2 x 5
Option 3)
5 x 2
Option 4)
5 x 5
