"units" is satisfactory for units of measurement if no more specific choice is made.
We are told that the perimeter of this square is 48 units. That would be equal to 4s units, where s is the length of any one side of this square.
Thus, 48 units = 4(s units), or 48 units = 4s. Then the side of the square has length s = 48 units / 4 = 12 units.
Check: If the length of one side is 12 units, what is the perimeter?
Answer: P = 4(12 units) = 48 units. Correct!
is
real and
rational.
For it to be an integer, whole, or natural number, it would have to be a whole number. Since it can be written as a repeating decimal (.6666666...) it is not irrational either.
