A rectangle and a square of equal area have larger sides

A rectangle and a square of equal area have larger sides

For example:
For example, if the length of a rectangle is 4.5 cm and the width is 2 cm, then the area of the rectangle is 9 square cm and the perimeter is 13.4 cm;
Then the side length of the square is 3cm, the area of the square is 9cm, and the perimeter is 12cm
So the circumference of the rectangle is bigger
It's wrong. It should be a rectangle
