Karen’s new dog pen will have the dimensions shown in the following image. Which number sentence shows the area of her dog pen?

area = length * width

Part A. The first one is 40

Part B. Then the second one is 52

One side is 5ft the other is 8ft

To find the area of the dog pen, we need to multiply the length by the width. The length is the longer side, which is 10 feet, and the width is the shorter side, which is 6 feet. Therefore, the number sentence that shows the area of the dog pen is:

10 feet × 6 feet = 60 square feet
