Beautiful problem !
The circle has more area.
If you have a circle and a square, with the circumference of the circle equal to
the perimeter of the square, then the area of the circle is always
(4/pi) = 1.27324
times as much as the area of the square.
If you have some length of fence in your warehouse, the most land you can
enclose with it is to set it up in a circle.
The perimeter of a 900 square centimeter square is 120 centimeters.
The perimeter would be 40cm.
8cm.
Its perimeter is: 4*6 = 24 cm
It is not. If you draw yourself a square then inscribe a circle with a radius of half the length of a side of the square, the circle will fit inside the square but the corners of the square will be outside the circle. Thus by inspection the area of the square is larger than the area of the circle.
28 cm
20 cm

Measure the square's in, Area, Perimeter and centimeter squared
Area = 6*6 = 36 square cm Perimeter = 4*6 = 24 cm
P = 40cm
20 cm
