The correct option is C The area of the circle is greater
Let the length of a side of square be a and radius of the circle is r.
Since square and circle have the same perimeter.
∴2πr=4a or r=2aπ
∴Area of the circleArea of the square=πr2a2=π.4a2π2a2=4π>1
Hence, area of the circle is greater than area of the square.
