Final answer:
Using generic rectangles, we can represent a multiplication problem by breaking down the numbers into their place values and arranging them in a rectangle. Then, we find the sum of each column and row to get the final product.
Step-by-step explanation:
Using generic rectangles, we can represent a multiplication problem by breaking down the numbers into their place values and arranging them in a rectangle. Let's demonstrate this with the given multiplication problems:
a. 54 • 32:
50 4 30 2____________ 160 8
b. 91 • 78:
90 1 70 8____________ 630 8
In both cases, we break down the numbers into their tens and ones place, create a rectangle, and then find the sum of each column and row to get the final product
