What happens when you run it? What should it do that it is not doing? Are there runtime errors? A stacktrace perhaps?

these go together
public class periArea extends JFrame {
Container pane = getContentPane();

and these go together
JFrame frame;
frame.setTitle("Area and Perimeter");

the two are not the same JFrame - you should be able to work out the fix.

when fixed, your next question will be "only row3 shows" - JFrame's default
LayoutManager is BorderLayout - read the apidocs for BorderLayout to see how
multiple components should be added.
It is sorta covered in the JavaRanch Style Guide.
