Those would be the prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47

a rectangle doesn't have four equal sided measurements, which is the definition of a square. also it can take one or more squares to make a rectangle but u can't make a rectangle into a square.
Only three sides is one possible answer.
In order to know the perimeter of a rectangle, you need to know both its length and its width ... two numbers. One number isn't enough. If one side of a rectangle is 22 feet, then the perimeter of the rectangle can be any number greater than 44 feet. There are an infinite number of different possibilities.
Two tiles can only make one rectangle.

prime numbers
A number can be made into only one rectangle if it is a square number. A square number is a number that can be represented as the product of an integer with itself, such as 1, 4, 9, 16, and so on. These numbers have only one unique way of arranging their factors to form a rectangle, as the sides will be equal in length.

If you can arrange the counters in the shape of a rectangle with at least two in each row and each column then the number is composite. The numbers of row and the numbers of columns are factors of the given number. If the only rectangle you can make is the "degenerate" one, with only one row or only one column, then the number is prime.
If you can make more than one rectangle, it's a composite number. If you can only make one, it's prime.
If you can only make one rectangle, your number's prime. If you can make more than one, it's composite.
Any prime can be made into only one rectangle. Any composite number can always be made into at least two different rectangles.

Because prime numbers only have one factor pair.
any fifty numbers can be made into 1 rectangle
