\n" );
document.write( "the middle length side is 3 more than the shortest side, 
\n" );
document.write( "and the longest side is double the middle length side.
\n" );
document.write( "Let x, (x+3), 2(x+3) represent the shortest, middle and longest lengths
\n" );
document.write( "Question states***
\n" );
document.write( " x + (x+3)+ 2(x+3)= 45cm
\n" );
document.write( "Solving for x
\n" );
document.write( "     4x = 36
\n" );
document.write( "      x = 9cm, the shortest.  the middle length is 12cm and longest 24cm
\n" );
document.write( "CHECKING our Answer***
\n" );
document.write( "  9cm + 12cm + 24cm =  45cm \n" );
document.write( "

\n" );
