Two circles with the same center(R=2, r=1). Now eqaulaly divide the circumference by 2*N points (the same way for large and small circles) and the points labled as follows: Large circle: L_1,L_2,...,L_2N Small circle: S_1,S_2,...,S_2N L_1,S_1,S_2,L_2,L_3,S_3...,S_2N-1,L_2N,L_1 forms a closed polygon with area=2.5*pi for all N. But the perimeter goes to infinite as you increase N.www.ddhw.com
