Sure. Take the fourth power of any natural number, for example 24 = 16. It square root is a perfect square, in this case 22. As another example, the square root of 34 = 32.
If the area of a square is 16 square inches, the perimeter is 16 inches.
If the given dimensions are in feet then 16 times 16 = 256 square feet
It is a natural number, an integer, a perfect square, a perfect fourth power, a rational number, a real number, ... and so on.
21
I am assuming that you mean the square root, in which case, the answer is no. An integer is a whole number, no decimals and can be positive or negative.
