How do you multiply using an area model. Example of multiplication problem with the area model. Area Model Multiplication Area of a shape is the space occupied by the shape. On this lesson you will learn how to use area model multiplication to solve multiplicative comparison word problems.

We are going to look at how to solve the multiplication problem 24 x 35. The area of the given rectangle is the shaded part. Draw a 2 2 grid that is a box with 2 rows and 2 columns.

Draw your grid and partition your numbers into tens and ones. Apply the distributive property of multiplication. Now just multiply the numbers as you usually would in ordinary multiplication.

Start by multiplying the tens from each number together and then multiply. Step 2 Start by multiplying the tens from each number together and then multiply the tens from each number by the ones so. Write the multiplicands in expanded form as tens and ones.

In this lesson you will learn how to multiply decimals by decimals by using an area model. Following the colors used on the graph the tens colored blue and the ones yellow when you multiply. To begin you need to represent this multiplication on a rectangle with sides 24 and 35.

Multiplication of Polynomials on a GridArea Model. For example 27 as 20 and 7 and 35 as 30 and 5. Then hold up 2 rulers and ask how many inches.

Now draw several rectangles marking each part separately in order to separate the tens. So lets go back to the grid and multiply those same two polynomials together x 4 and x 5 you might want.
