Let's see. Perimeter is the distance around the plane.
\n" ); document.write( "So, we just add the sides:
\n" ); document.write( "\"+%284x+%2B+1%29+%2B+%287x+-+2%29+%2B+%287x+%2B+1%29+\"
\n" ); document.write( "And we combine like terms:
\n" ); document.write( "\"+%284x+%2B+7x+%2B+7x%29+%2B+%281+%2B+%28-2%29+%2B+1%29+\"
\n" ); document.write( "And add:
\n" ); document.write( "\"+18x+%2B+0+\"
\n" ); document.write( "Remove the zero:
\n" ); document.write( "\"+18x+\"
\n" ); document.write( "And there's your final answer!\r
