The length of the sides of triangle are in the rtio of 3 to 5 to 6. if the perimeter of the triangle is 70, what is the length f the longest side?

\r\n" );
document.write( "We know there is a constant k that we can multiply each of those three\r\n" );
document.write( "numbers, 3, 5, and 6 by such that their sum which will be the perimeter,\r\n" );
document.write( "will be 70, so we have this equation:\r\n" );
document.write( "\r\n" );
document.write( "Smallest side = 3k\r\n" );
document.write( "Medium-sized side = 5k\r\n" );
document.write( "Largest side = 6k \r\n" );

document.write( "Smallest side = 3k = 3(5) = 15\r\n" );

document.write( "Largest side = 6k = 6(5) = 30\r\n" );
document.write( "\r\n" );
document.write( "Perimeter = 15 + 25 + 30 = 70\r\n" );
document.write( "\r\n" );
document.write( "You wanted the longest side, so the answer is 30.\r\n" );
