Recall that the formula for perimeter is \"+p+=+2l+%2B+2w\".\r
\n" ); document.write( "\n" ); document.write( "In the problem it is stated that w = 10. And l is defined as 3w-4. Since w is 10, then l must be 3*10 -4 = 26. \r
\n" ); document.write( "\n" ); document.write( "We have:\r
\n" ); document.write( "\n" ); document.write( "\"+l+=+26+\"
\n" ); document.write( "\"+w+=+10+\"\r
\n" ); document.write( "\n" ); document.write( "Now it's time to plug and chug.\r
\n" ); document.write( "\n" ); document.write( "\"p+=+2%2A26+%2B+2+%2A10++=+52%2B20+=+72\" inches.
