When looking for a perimeter we are actually looking for a distance, so we can use the look at this problem in parts.\r
\n" ); document.write( "\n" ); document.write( "The distance between each point can be found by using the formula:\r
\n" ); document.write( "\n" ); document.write( "\"d=sqrt%28%28X-x1%29%5E2%2B%28Y-y1%29%5E2%29\"\r
\n" ); document.write( "\n" ); document.write( "distance1= \"d=sqrt%28%28-5-7%29%5E2%2B%28-3-2%29%5E2%29\"=13
\n" ); document.write( "distance2 =\"d=sqrt%28%28-5-4%29%5E2%2B%28-3-6%29%5E2%29\"=12.7279
\n" ); document.write( "distance3=\"d=sqrt%28%287-4%29%5E2%2B%282-6%29%5E2%29\"=5\r
\n" ); document.write( "\n" ); document.write( "the perimeter = 13+12.7279+5 = 30.7279
