document.write( "Let \"a\"be the length of the side of this equilateral triangle.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "For any equilateral triangle, there is well known expression for the height\r\n" );
document.write( "\r\n" );
document.write( "    h = \"a%2A%28sqrt%283%29%2F2%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence,  in our case  \"a%2Asqrt%283%29%2F2%29%29\" = \"2%2Asqrt%283%29\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It gives for \"a\"  a = \"4\".\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the perimeter is 3a = 3*4 = 12 cm.    ANSWER.\r\n" );
