Let w = the width, and 2w = the length. Set up an equation.\r
\n" ); document.write( "\n" ); document.write( "\"2%28w%2B2w%29=30\"
\n" ); document.write( "\"2w%2B4w=30\"
\n" ); document.write( "\"6w=30\"
\n" ); document.write( "\"w=5\"
\n" ); document.write( "\"5%2A2=10\"\r
\n" ); document.write( "\n" ); document.write( "Width = 5 units, Length = 10 units
\n" ); document.write( "
