\n" ); document.write( "My preferred approach to this problem is to convert the given information to say the ratio of length to width is 3:2. Then

\n" ); document.write( "let 3x = length
\n" ); document.write( "let 2x = width

\n" ); document.write( "The perimeter (twice length plus twice width) is 30m:

\n" ); document.write( " $\"2%283x%29%2B2%282x%29+=+30\"$
\n" ); document.write( " $\"10x+=+30\"$
\n" ); document.write( " $\"x+=+3\"$

\n" ); document.write( "ANSWERS:
\n" ); document.write( "length 3x = 9m
\n" ); document.write( "width 2x = 6m

\n" ); document.write( " \n" ); document.write( "
