Oliver is building a rectangular dog pen with an area of 18.9 square feet. If the length of the dog pen is 6.3 feet, what is the width?
To find the width of the rectangular dog pen, we can divide the area by the length.
Width = Area / Length
Width = 18.9 square feet / 6.3 feet = 3 feet.
Therefore, the width of the dog pen is 3 feet.
