X=S+18
\n" ); document.write( "Y=3S-11
\n" ); document.write( "X+Y+S=137
\n" ); document.write( "S+18+3S-11+S=137
\n" ); document.write( "5S=137-18+11
\n" ); document.write( "5S=130
\n" ); document.write( "S=130/5
\n" ); document.write( "S=26 FT. FOR THE SHORTEST SIDE.
\n" ); document.write( "X=26+18=44 FT. FOR THE MIDDLE SIDE.
\n" ); document.write( "Y=3*26-11=78-11=67 FT. FOR THE LONGER SIDE.
