\r\n" );
document.write( "You are given that  = .\r\n" );
document.write( "\r\n" );
document.write( "Hence, D = .\r\n" );
document.write( "\r\n" );
document.write( "As everybody knows, the diagonal of a square is D = , where a is the square side.\r\n" );
document.write( "\r\n" );
document.write( "Hence, a = 10 in our case.\r\n" );
document.write( "\r\n" );
document.write( "Then the perimeter of the square is 4*10 = 40 cm.\r\n" );
