W=width; L=length=3W-4; A=area; P=perimeter
\n" ); document.write( " $\"A=LW\"$ = $\"%283W-4%29%28W%29=3W%5E2-4W\"$
\n" ); document.write( "ANSWER 1: Area is $\"3W%5E2-4W\"$
\n" ); document.write( " $\"P=2%28L%2BW%29\"$ = $\"2%283W-4%2BW%29=8W-8\"$ = $\"8%28W-1%29\"$
\n" ); document.write( "ANSWER 2: The perimeter is 8(W-1) \n" ); document.write( "
