\r\n" );
document.write( "Let X be the square side length, now unknown.\r\n" );
document.write( "\r\n" );
document.write( "Then the perimeter is P = 4X, while the area is A = X^2.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "They want  A = 4P,   or  X^2 = 4*(4X),  which is the same as  X^2 = 16*X.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Divide by X both sides of the last equation, and you will get\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    X = 16.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is your ANSWER :  The side length must be  16 units long.\r\n" );
