2L + 2W = perimeter (think of a perimeter as a fence around the rectangle)
\n" ); document.write( "W = 20
\n" ); document.write( "2L + 2(10) = 56
\n" ); document.write( "2L + 20 = 56
\n" ); document.write( "subtract 20 from each side
\n" ); document.write( "2L = 36
\n" ); document.write( "Divide each side by 2
\n" ); document.write( "L = 18
\n" ); document.write( "
\n" );
