Let w = width and L = length.
\n" ); document.write( "\"L=2w-5\" and \"50%3E2w%2B2L%3E36\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Wanting the longest length, first solve for w in terms of L.
\n" ); document.write( "\"2w=L%2B5\"
\n" ); document.write( "\"w=%28L%2B5%29%2F2\", and substitute this into the inequality.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"50%3E2%28L%2B5%29%2F2%2B2L%3E36\"
\n" ); document.write( "\"50%3EL%2B5%2B2L%3E36\"
\n" ); document.write( "\"50%3E3L%2B5%3E36\"
\n" ); document.write( "\"50-5%3E3L%3E36-5\"
\n" ); document.write( "\"45%3E3L%3E29\"
\n" ); document.write( "\"29%2F3%3CL%3C45%2F3\"
\n" ); document.write( "\"highlight%2829%2F3%3CL%3C15%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For the LONGEST possible rectangle, L can be as near to 15 as desired but still must be less than 15. A suitable value for w can then be found in order to agree with the inequality.
