What is the output of the following code? Assume the Rectangle class exists and all the methods called below exist and work as expected.
ArrayList blah = new ArrayList ();
blah.add( new Rectangle(3,5) );
blah.add( new Rectangle(2,15) );
blah.add( new Rectangle(5,5) );
double x=0;
System.out.println(blah.size());
for(Rectangle s: blah) x+=s.area();
