The strategy of drawing rectangles is very flexible. Try using it for the multiplication problem 193 times 37. To break down 193, think of it as 200 minus 7. Similarly, break down 37 as 30 plus 7. How can you use this strategy to find the product of 193 and 37?
A) By multiplying 200 and 30, then adding 7
B) By multiplying 200 and 37, then subtracting 7
C) By multiplying 193 and 30, then adding 7
D) By multiplying 193 and 37, then subtracting 7
