If each inner square has a perimeter of 20, then their sides must be 20/4, or 5.
\n" ); document.write( "Think of it like a window pane, with the window cut into four equal pieces. If one pane is 5 by 5, then the top measurement would be 5 * 2 (2 panes wide) and the side measurement would also be 5 * 2 (2 panes long). The window is 10 by 10. Its perimeter is twice the length (10*2) + twice the width (10*2). 20+20 = 40
