The area of the rectangle is
\n" ); document.write( "\"A=L%2AW\"
\n" ); document.write( "\"L=140%2B2W\"
\n" ); document.write( "\"A=%28140%2B2W%29W\"
\n" ); document.write( "The area of the square is,
\n" ); document.write( "\"A=s%5E2=60%5E2=3600\"
\n" ); document.write( "Equate the areas,
\n" ); document.write( "\"W%282W%2B140%29=3600\"
\n" ); document.write( "\"2W%5E2%2B140W-3600=0\"
\n" ); document.write( "\"W%5E2%2B70W-1800=0\"
\n" ); document.write( "Factor,
\n" ); document.write( "\"%28W%2B90%29%28W-20%29=0\"
\n" ); document.write( "Only the positive result makes sense here.
\n" ); document.write( "\"W-20=0\"
\n" ); document.write( "\"W=20\"ft.
\n" ); document.write( "\"L=140%2B40=180\"ft.
\n" ); document.write( "
\n" );
