L=length; W=width; P=perimeter=308 meters; A=area=5785 square meters
\n" ); document.write( "\"P=2%28L%2BW%29\"
\n" ); document.write( "\"308m=2%28L%2BW%29\" Divide each side by 2.
\n" ); document.write( "\"154m=L%2BW\"
\n" ); document.write( "\"154m-W=L\" Use this to substitute for L.
\n" ); document.write( "\"A=LW\"
\n" ); document.write( "\"5785m%5E2=LW\" Substitute for L.
\n" ); document.write( "\"5785m%5E2=%28154m-W%29%28W%29\"
\n" ); document.write( "\"5785m%5E2=154W-W%5E2\" Subtract 5785 sq m from each side.
\n" ); document.write( "\"0=-W%5E2%2B154W-5785m%5E2\"
\n" ); document.write( "\"0=-1%28W-65%29%28W-89%29\"
\n" ); document.write( "\"W-65=0\" or \"W-89=0\"
\n" ); document.write( "\"W=65\" or \"W=89\" ANSWER: The width is 89m or 65m.
\n" ); document.write( "\"L=154m-W\"
\n" ); document.write( "\"L=154m-65m\" or \"L=154m-89m\"
\n" ); document.write( "\"L=89m\" or \"L=65m\" ANSWER: The length is 65m or 89m.
\n" ); document.write( "The dimensions of the parking lot are 65 meters by 89 meters.
\n" ); document.write( "CHECK:
\n" ); document.write( "\"A=LW\"
\n" ); document.write( "\"5785m%5E2=%2865m%29%2889m%29\"
\n" ); document.write( "\"5785m%5E2=5785m%5E2\"
\n" ); document.write( "
\n" );
