2W + 2L = P where W is width, L is length and P is perimeter
\n" ); document.write( "L = 4W Substitute 4W for L and 80 for P
\n" ); document.write( "2W + 2(4W) = 80
\n" ); document.write( "2W + 8W = 80
\n" ); document.write( "10W = 80
\n" ); document.write( "W = 8
\n" ); document.write( "L = 4W = 4(8) = 32\r
