The dimension of PQ is the product of the number of raws of matrix P to the number of columns of the matrix Q. Then the dimension of the matrix PQ is 3 X 5.
The dimensions of a matrix are the product of the number of raw and the number of columns, which is known as a dimension of a matrix.
Matrix P has dimensions of 3 X 4 and Matrix Q has dimensions 4 X 5.
Then we have to determine the dimension of PQ.
We know that the dimension of PQ is given as the product of the number of raws of matrix P to the number of columns of the matrix Q.
Then the dimension of the matrix PQ is 3 X 5.
