Let a be the side of a square plot
\n" ); document.write( "perimeter = 320 feet
\n" ); document.write( "4a = 320
\n" ); document.write( "a=320/4 = 80
\n" ); document.write( "a=80
\n" ); document.write( "by Pythagorean theorem
\n" ); document.write( "a^2 + a^2 =(diagonal)^2
\n" ); document.write( "80^2 + 80^2 = (diagonal)^2
\n" ); document.write( "6400 + 6400 =(diagonal)^2
\n" ); document.write( "12800 = (diagonal)^2
\n" ); document.write( "diagonal = sq rt(12800) = 11.314
\n" ); document.write( "diagonal = 11.314
\n" ); document.write( "
\n" );
