You can put this solution on YOUR website!
Start with the formula for the perimeter of a rectangle:
\n" ); document.write( "\"P+=+2L%2B2W\"
\n" ); document.write( "In your problem, P = 40ft.
\n" ); document.write( "\"W+=+L%2F2+%2B+2\"
\n" ); document.write( "\"L+=+L\"
\n" ); document.write( "Substitute these into the basic formula above:
\n" ); document.write( "\"40+=+2L+%2B+2%28L%2F2+%2B+2%29\" Simplify and solve for L
\n" ); document.write( "\"40+=+2L+%2B+L+%2B+4\"
\n" ); document.write( "\"40+=+3L+%2B+4\" Subtract 4 from both sides of the equation.
\n" ); document.write( "\"36+=+3L\" Divide both sides by 3.
\n" ); document.write( "\"12+=+L\"
\n" ); document.write( "The length is 12ft.
\n" ); document.write( "The width is\"L%2F2%2B2+=+12%2F2+%2B+2\" = 8ft.
\n" ); document.write( "Check:
\n" ); document.write( "\"P+=+2L%2B2W\"
\n" ); document.write( "\"P+=+2%2812%29%2B2%288%29\"
\n" ); document.write( "\"P+=+24%2B16\"
\n" ); document.write( "\"P+=+40\" It checks!
\n" ); document.write( "
\n" );
