Square constant – Any even number greater than4 is the side of the square.
If the perimeter and the area are calculated, then the perimeter is subtracted by the area and the result got will be always a multiple of 4.

Here is a square of side of 12 cm. Area= 12 * 12 = 144
Perimeter =12 * 4= 48
144- 48 = 96 and 96 is a multiple of 4.
Therefore, any even number greater than4 is the side of the square. If the perimeter and the area are calculated, then the perimeter is subtracted by the area and the result got will be always a multiple of 4.
