\n" ); document.write( "W=width; L=length=3W-5cm; A=area=112cm^2
\n" ); document.write( ".
\n" ); document.write( "\"LW=A\"
\n" ); document.write( "\"%283W-5cm%29%28W%29=112cm%5E2\"
\n" ); document.write( "\"3W%5E2-5Wcm=112cm%5E2\"
\n" ); document.write( "\"3W%5E2-5Wcm-112cm%5E2=0\"
\n" ); document.write( "\"%28W-7%29%283W%2B16%29=0\"
\n" ); document.write( "\"W-7=0\" \"OR%29%29%29+%7B%7B%7B3W%2B16=0\"
\n" ); document.write( "\"W=7\" \"OR\" \"3W=-16\"
\n" ); document.write( "\"W=7\" \"OR\" \"W=-%2816%2F3%29\"
\n" ); document.write( "ANSWER 1: The width is 7 cm.
\n" ); document.write( ".
\n" ); document.write( "\"L=3W-5cm\"
\n" ); document.write( "\"L=3%287cm%29-5cm\"
\n" ); document.write( "\"L=21cm-5cm\"
\n" ); document.write( "\"L=16cm\"
\n" ); document.write( "ANSWER 2: The length is 16 cm.
\n" ); document.write( ".
\n" ); document.write( "CHECK:
\n" ); document.write( "A=LW
\n" ); document.write( "112cm^2=(16cm)(7cm)
\n" ); document.write( "112cm^2=112cm^2
\n" ); document.write( "
\n" );
