You probably started out with a picture and labeling length Y and width 5; always a good first step to understanding the problem.
\n" ); document.write( "The perimeter formula is
\n" ); document.write( " $\"P+=+2L+%2B+2W\"$
\n" ); document.write( "we know length is Y and width is 5, so we put in Y and 5 to get
\n" ); document.write( " $\"P+=+2Y+%2B+2%285%29\"$
\n" ); document.write( "Now the perimeter is given to us as 34, so,
\n" ); document.write( " $\"34+=+2Y+%2B+10\"$
\n" ); document.write( "Solve for Y to get
\n" ); document.write( " $\"24+=+2Y\"$
\n" ); document.write( "12 = Y.
\n" ); document.write( "The length of the rectangle is 12 cm.
\n" ); document.write( " \n" ); document.write( "
