Let's see.
\n" ); document.write( "360/3 = 120
\n" ); document.write( "225/3 = 75 \r
\n" ); document.write( "\n" ); document.write( "P = 2 times width plus 2 times length.
\n" ); document.write( "P = 2(75) + 2(120) \r
\n" ); document.write( "\n" ); document.write( "P = 150 + 240 \r
\n" ); document.write( "\n" ); document.write( "P = 390 \r
\n" ); document.write( "\n" ); document.write( "He will need 390 fences.
\n" ); document.write( "
