2w + 2l = 72
\n" ); document.write( "2h + 2l+18 = 114
\n" ); document.write( "-18 -18
\n" ); document.write( "2h + 2l = 96
\n" ); document.write( "(96 - 72 = 24)
\n" ); document.write( "2h = 24
\n" ); document.write( "h = 12
\n" ); document.write( "w = 12
\n" ); document.write( "24 + 2l = 72
\n" ); document.write( "2l = 48
\n" ); document.write( "l = 24\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "length is 24
\n" ); document.write( "width is 12
