28 is not a perfect square. A perfect square is an integer that is the square of another integer. 9 is a perfect square; it equal to 3 squared, or 3 X 3. Often, such numbers are called simply square numbers. While 28 is not a perfect square, it is a square number in the sense that it has a square root. by definition, the square root of 28 times itself equals 28.
It is 2.

A negative integer. Every time.
No, a perfect square is the square of an integer number. Fractions are never a perfect square, as the square of an integer is always another integer.Actually fractions can be perfect squares an example is one ninth, it would be one third times one third which equals one ninth.
That has no integer solution. Three times an integer is another integer; if you subtract to integers, you get an integer again, not a fraction.

Yes. The square of an integer is just the number times itself. For any two whole numbers that are multiplied, the answer is always an integer (i.e. no decimals).
