w, width of plot
\n" ); document.write( "L, length of plot
\n" ); document.write( "u, UNIFORM width border around plot
\n" ); document.write( ";
\n" ); document.write( "w=10
\n" ); document.write( "L=15\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"wL\", area of the plot.
\n" ); document.write( "\"%28w%2B2u%29%28L%2B2u%29\", area of the plot AND the walkway.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The wording of the last part of the description means that the total area is two times the plot area; and the question is, find u.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight_green%28%28w%2B2u%29%28L%2B2u%29=2wL%29\"
\n" ); document.write( "Solve for u, and plug in the given values.
