document.write( "Obviously, their centers (in the section) form equilateral triangle with the side length of 10 cm.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, add 10 + 10 + 10 = 30 centimeters for linear elements first. \r\n" );
document.write( "\r\n" );
document.write( "Then add to it three times the length of the arc of the circle of the radius 5 cm and the central angle of 120 degrees.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the final answer is   =  centimeters.\r\n" );
