Describe how to model 2-digit by 2-digit multiplication using an area model (short explanation) 20 points

First, have your numbers lined up like so --->     25
                                                                                12
                                                                             
 Always have the larger number on top. First multiply 2 x 5. add the number in the tens place to the result of the 2nd step. Multiply 2x2. So now you should have this.
25
12

50                Then have a placeholder below in the one's spot
  x          Then do the same but with the but with the second number, so you have
25
12

 50
500

Then add the two bottom numbers together and boom you done
