Answer :
Option B:
Size of the matrix resulting form = (1 × 3)
Solution:
The dimensions of a matrix is always represented by the number of rows and the number of columns in the matrix.
Here, number of rows of the first matrix = 1
Number of columns of the first matrix = 3
Therefore, the size of the first matrix = ( 1 × 3)
number of rows of the second matrix = 3
Number of columns of the second matrix = 3
Therefore the size of the second matrix = ( 3 × 3)
Now, to find the size of the matrix after doing multiplication.
In general form of the size of matrix multiplication
= (a × b) × (b × c)
= (a × c)
Here, size of the matrix resulting form
= ( 1 × 3) × ( 3 × 3)
= (1 × 3)
Option B is the correct answer.
Hence size of the matrix resulting form is (1 × 3).
