\n" ); document.write( "we have the perimeter. 54=(2L+3)+2W. Is this right? I'm stuck!

54 = 2H+2W (Height and Width) Length would work the same, but it says height.
\n" ); document.write( "2H = W+3, so W = 2H - 3\r
\n" ); document.write( "\n" ); document.write( "Sub for W\r
\n" ); document.write( "\n" ); document.write( "54 = 2H + 2(2H-3)
\n" ); document.write( "54 = 2H + 4H - 6
\n" ); document.write( "60 = 6H
\n" ); document.write( "H = 10
\n" ); document.write( "W = 17
\n" ); document.write( "
\n" ); document.write( "
\n" );
