You can put this solution on YOUR website!
S = 2WL + 2LH + 2WH; (solve for L)
\n" ); document.write( ":
\n" ); document.write( "Subtract 2WH from both sides:
\n" ); document.write( "S - 2WH = 2WL + 2LH
\n" ); document.write( ":
\n" ); document.write( "Factor out L on the right:
\n" ); document.write( "S - 2WH = L(2W + 2H)
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by (2W+2H)
\n" ); document.write( "L = \"%28%28S-2WH%29%29%2F%28%282W%2B2H%29%29\"
\n" ); document.write( "
\n" );
