Question

A matrix with 5 columns and 6 rows added to another matrix with 5 columns and 6
rows would result in a matrix with:
A. 12 columns and 10 rows B.5 columns and 6 rows. C 10 columns and 12 rows. D. 6 columns and 5 rows

Answer 1

Option B - 5 columns and 6 rows is the correct answer

Step-by-step explanation:

Step 1 :

Given,

Number of columns of first matrix = 5

Number of rows of  first matrix = 6

Number of columns of second matrix = 5

Number of rows of  second matrix = 6

We need to determine number of rows and columns of the resultant matrix.

Step 2 :

When  a matrix of dimension m × n is added to another m × n matrix, the resultant matrix is also a m × n matrix.

Hence when a matrix with 5 columns and 6 rows added to another matrix with 5 columns and 6  rows the resultant matrix will also have 5 columns and 6 rows.

Step 3 :

Answer :

Option B - 5 columns and 6 rows is the correct answer
