Answer

The resulting matrix is therefore [11717]

Steps

Step 1 :Multiply the first row of A by the first column of B: (21)+(33)=2+9=11

Step 2 :Multiply the first row of A by the second column of B: (22)+(31)=4+3=7

Step 3 :Multiply the second row of A by the first column of B: (41)+(13)=43=1

Step 4 :Multiply the second row of A by the second column of B: (42)+(11)=81=7

Step 5 :The resulting matrix is therefore [11717]
