Well, the perimeter of the square is 72/2 = 36 inches = p. The sides of the square are thus p/4 = 36/4 = 9 inches. So what is the area of the square?
Similarly the circumference of the circle is 72/2 = 36 inches. Now recall the perimeter of the square: p = 36 inches. Thus C = 2 (pi) r = p.
Can you finish this?

Hi Dan!
Thanks a lot for the reply.
I still don't really get it though, I can't seem to get the answer given.
See:
Area of the square = (p/4)^2
r of the circle = p/2pi
Area of the circle = pi(p/2pi)^2
Is that correct so far? Thus A would be area of square + area of circle right? That's where I get stuck, cos I can't seem to get the answer from there.
Thanks again,
Eugene
