To find \( 4 \times 7 \), break it into \( 4 \times 3 + 4 \times 4 \), which equals \( 12 + 16 = 28 \).

Solución

To represent \( 4 \times 7 \) using an area model and the distributive property, we can break it apart as follows: 1. **Area Model Representation**: - We can visualize \( 4 \times 7 \) as a rectangle where one side is 4 units long and the other side is 7 units long. 2. **Breaking it Apart**: - We can break \( 7 \) into two parts: \( 3 \) and \( 4 \). Thus, we can express \( 4 \times 7 \) as: \[ 4 \times (3 + 4) \] 3. **Using the Distributive Property**: - According to the distributive property, we can distribute \( 4 \) to both \( 3 \) and \( 4 \): \[ 4 \times 7 = 4 \times 3 + 4 \times 4 \] 4. **Calculating Each Part**: - Now, we calculate each part: - \( 4 \times 3 = 12 \) - \( 4 \times 4 = 16 \) 5. **Final Calculation**: - Adding these two results together gives: \[ 12 + 16 = 28 \] Thus, the area model shows that \( 4 \times 7 = 28 \) and can be broken apart using the distributive property as \( 4 \times 3 + 4 \times 4 \).

To visualize \( 4 \times 7 \) using an area model, imagine a rectangle where one side measures 4 units (representing the multiplicand) and the other side measures 7 units (the multiplier). Now, applying the distributive property, we can break apart the 7 into two parts: \( 4 \) and \( 3 \), giving us \( 4 \times (4 + 3) \). This creates two smaller rectangles within the larger one: a \( 4 \times 4 \) rectangle and a \( 4 \times 3 \) rectangle. The area of the first rectangle is \( 16 \) square units and the area of the second rectangle is \( 12 \) square units. Adding these together, the total area (or the product \( 4 \times 7 \)) equals \( 28 \) square units! Now, here's a fun twist: picture this area model on a pizza, where \( 4 \) represents your friends and \( 7 \) symbolizes the slices – everyone gets a share of that delicious \( 28 \) slice feast! 🍕
