Nope, that won't get you there.\r
\n" ); document.write( "\n" ); document.write( "Given: Perimeter = 144M and length is 9 m more than twice the width.\r
\n" ); document.write( "\n" ); document.write( "\"P+=+2L+%2B+2W\" = 144
\n" ); document.write( "\"L+=+2W+%2B+9+\"\r
\n" ); document.write( "\n" ); document.write( "\"144+=+2L+%2B+2W\"
\n" ); document.write( "\"144+=+2%282W%2B9%29+%2B+2W+\"
\n" ); document.write( "\"144+=+4W+%2B+18+%2B+2W\"
\n" ); document.write( "\"126+=+6W\"
\n" ); document.write( "W = 21
\n" ); document.write( "So L = 51\r
\n" ); document.write( "\n" ); document.write( "Check you answer. Does 144 = 2*51 + 2*21???
\n" ); document.write( "
\n" ); document.write( "
