MCQ
Two matrices $A$ and $B$ are added if:
  • A
    Both are rectangular
  • ✓
    Both have same order
  • C
    No of columns of $A$ is equal to columns of $B$
  • D
    No of rows of $A$ is equal to no of columns of $B$
✓

Answer

Correct option: B.
Both have same order
While adding two matrices we add the numbers which belong to some row and column of each matrixo two matrices can be added.
If there are equal number of rows and columns in both. Both matrices should have same order therefore.
