12(4+2f)=

Answer 1

To use the area model to multiply \(12(4 + 2f)\), we can break this down using the distributive property.

Step 1: Set up the area model

We can think of \(4 + 2f\) as two separate parts: \(4\) and \(2f\). This gives us two rectangles to work with.

Step 2: Create the partial products

• The first rectangle will represent \(12 \times 4\).
• The second rectangle will represent \(12 \times 2f\).

Calculate each product:

1. First rectangle: \[ 12 \times 4 = 48 \]

2. Second rectangle: \[ 12 \times 2f = 24f \]

Step 3: Find the total area

Now we can combine the two areas (partial products):

\[ 48 + 24f \]

Step 4: Write the final product

So, the final product of \(12(4 + 2f)\) is: \[ 12(4 + 2f) = 48 + 24f \]
