karen's new dog pen will have the dimensions shown as in the following image which number sentence should the area of her dog pen

To determine the area of Karen's dog pen, we need to multiply the length and the width of the pen. Since you mentioned there's an image with the dimensions, I'll assume you have the values.

1. Look at the image or information provided. Find the length and width values for the dog pen.

2. Once you have the length and width, multiply these two numbers together.

3. Write the number sentence for finding the area using the multiplication operator (×).

For example, if the length of the dog pen is 5 feet and the width is 3 feet, the number sentence for finding the area would be:

Area = Length × Width
Area = 5 feet × 3 feet

So, the number sentence for the area of Karen's dog pen would be:

Area = Length × Width

Substitute the actual values for length and width to get the specific number sentence.
