Let x = width
\n" ); document.write( "Then 3x - 2 = length.\r
\n" ); document.write( "\n" ); document.write( "We need 2 widths, and 2 lengths, for a perimeter of 6800cm (1m=100cm)\r
\n" ); document.write( "\n" ); document.write( " $\"2x+%2B+2%283x+-+2%29+=+6800\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x+%2B+6x+-+4+=+6800\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"8x+=+6804\"$ \r
\n" ); document.write( "\n" ); document.write( "x (width)=850.5
\n" ); document.write( "(length) = 2549.5\r
\n" ); document.write( "\n" ); document.write( "Proof: 850.5 + 850.5 + 2549.5 + 2549.5 = 6800.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
