draw a line between the furthest corners. you now have a right-triangle with two adjacent sides with length a=7 and b=4
\n" ); document.write( "use Pythagoras' theorem \"a%5E2%2Bb%5E2=c%5E2\"
\n" ); document.write( "to give \"c=sqrt%287%5E2%2B4%5E2%29\"
\n" ); document.write( "\"c=sqrt%2849%2B16%29\"
\n" ); document.write( "\"c=sqrt%2865%29ft\"\r
