Five squares of different dimensions are arranged in two ways as shown in the following diagrams. The numbers inside each square represents its area in square units. 

Calculate the perimeter $$A_1A_2A_3A_4A_5A_6A_7A_8A_9A_{10}A_{11}A_{12}A_1$$ and the corresponding perimeter of figure 2. Are they same? If they are different, which is greater?
