The perimeter of a rectangle is twice the length plus twice the width.

\n" ); document.write( " $\"P=2L%2B2W\"$
\n" ); document.write( "You want to set up an inequality,
\n" ); document.write( " $\"P%3E100\"$
\n" ); document.write( " $\"2L%2B2W%3E100\"$
\n" ); document.write( "In your case, the width is 10.
\n" ); document.write( " $\"2L%2B20%3E100\"$
\n" ); document.write( " $\"2L%3E80\"$
\n" ); document.write( " $\"L%3E40\"$
\n" ); document.write( "Any length greater than 40 cm will make the perimeter over 100 cm. \n" ); document.write( "
