Length = 3x
\n" ); document.write( "Width = x\r
\n" ); document.write( "\n" ); document.write( "Perimeter = 2(Length + Width)\r
\n" ); document.write( "\n" ); document.write( "\"74+=+2%283x%2Bx%29\"\r
\n" ); document.write( "\n" ); document.write( "\"74+=+8x\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+9.25\"\r
\n" ); document.write( "\n" ); document.write( "Area = Length * Width\r
\n" ); document.write( "\n" ); document.write( "\"A+=+%283%2A9.25%29%2A9.25+=+256.6875\" square meters
