the size of the resulting matrix is 1-by-3.
step-by-step explanation:
the size of the two matrices given are as follows:
no .of rows of matrix 1 = 1
no .of columns of matrix 1 = 3
no .of rows of matrix 1 = 3
no .of columns of matrix 1 = 3
to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:
if resulting matrix = matrix 1 * matrix 2
no. of rows of the resulting matrix = number of rows of matrix 1
no. of columns of resulting matrix = number of columns of matrix 2
note: the order of the matrices matter!
