THREE RECTANGULAR SECTIONS.
\n" ); document.write( "Dimensions x and y for the entire garden\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let y be the length of the house to use for one whole side of the garden.
\n" ); document.write( "If the two divider fence parts are parallel to the x dimension, then:\r
\n" ); document.write( "\n" ); document.write( "\"x%2Bx%2Bx%2Bx%2By=56\"\r
\n" ); document.write( "\n" ); document.write( "\"4x%2By=56\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Formula for garden area, A
\n" ); document.write( "\"A=xy\"
\n" ); document.write( "\"highlight_green%28A=x%2856-4x%29%29\"\r
\n" ); document.write( "\n" ); document.write( "You can use this formula to find the x for the maximum A, and use result to find y. (Maximum occurs in exact middle of the two zeros of A).

\n" );
