No. Consider the (perimeter) function where x is the length of a leg. This is equivalent to which is linear. The linear function is defined on all positive real numbers, and its range is all real numbers, including integers. Hence, it is possible for the perimeter to be an integer (for example, replace and you will find that the perimeter is 1).
