The correct response is:
No, because shapes can have the same perimeter but take up a different amount of space.
Explanation: Two different rectangles can have the same perimeter but different lengths and widths, which can result in different areas. For example, a rectangle with dimensions 1 foot by 9 feet (area = 9 square feet) and another rectangle with dimensions 4 feet by 6 feet (area = 24 square feet) can both have a perimeter of 20 feet, yet they have different areas. Thus, Sarah's statement is not correct.
