A red rectangle is reshaped into a blue square, as shown above, such that both quadrilaterals have the same perimeter, and the square is \(4\text{ cm}^2\) larger than the rectangle.
If all the sides of both quadrilaterals has length of a prime number (in \(\text{cm}\)), then what is the perimeter of the square?
