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