\n" ); document.write( "The longest side of the triangle is thrice the length of the shortest side.The medium-sized side is 4cm less than the longest side.The perimeter of the triangle is 31cm.how long is the longest side?
\n" ); document.write( "

Let longest side be L
\n" );
document.write( "Then shortest side = 
\n" );
document.write( "Middle side = L - 4
\n" );
document.write( "We then get:  =====> 
\n" );
document.write( "6L + L = 105 ------ Multiplying by LCD, 3
\n" );
document.write( "7L = 105
\n" );
document.write( "L, or longest side =  \n" );
document.write( "

\n" );
