*BEGINNER'S JAVA HELP*

Hello, I'm asking a question which pertains to a lab in my zyBooks, and I'm having trouble with a specific part to the entire lab (the 2nd part) after hacking at it by myself and a couple of my peers too.

Jane is planning to put a new fence around her flower garden. She wants to change the shape, but doesn't want to change the amount of space it occupies. It is currently a square that has sides of length squareSide. She wants to make it a rectangle with one set of parallel sides twice the length of the other set of parallel sides. What should the length of the sides be?

I'm assuming the only trouble would be the actual math near the end, can anyone help me and explain it too?

(Note: I turned two potential equation sets into comments + the only input is 5 for this part.)

/*Solution to Problem B Note: the squareroot function is Math.sqrt(variable) */ double squareSide = 0; double rectangleLength = 0; double rectangleWidth = 0; double area = 0; squareSide = scan.nextDouble(); area = Math.pow(squareSide, squareSide); rectangleWidth = squareSide / Math.sqrt(2.0); rectangleLength = squareSide/Math.sqrt(0.5); /* rectangleWidth = Math.sqrt(area / 2); rectangleLength = rectangleWidth * 2; */ /* rectangleLength = Math.sqrt(2 * rectangleLength) / 2; rectangleWidth = Math.sqrt(area / 2) * 2; */ rectangleLength = Math.sqrt(squareSide); System.out.print("Length of long side: " + rectangleLength); System.out.print(" "); System.out.printf("Length of short side: " + rectangleWidth); } }
