Let the perimeter be P. It equals 36.
\n" ); document.write( "Let W be width and L be length. So
\n" ); document.write( "P = 2L + 2W = 36
\n" ); document.write( "Now the other statement can be written as
\n" ); document.write( "L = 3 + 2W
\n" ); document.write( "Now substitute this into the first equation and get
\n" ); document.write( "2(3 + 2W) + 2W = 36
\n" ); document.write( "6 + 4W + 2W = 36
\n" ); document.write( "6 + 6W = 36
\n" ); document.write( "6W = 30
\n" ); document.write( "W = 5
\n" ); document.write( "and L = L = 3 + 2W = 3 + 2(5) = 13
\n" ); document.write( "
\n" ); document.write( "
\n" );
