<image>If the ABCDE shape is a combination of a rectangle and an equilateral triangle, the perimeter of the ABCDE shape is 72, the BCFG shape is a rectangle where a semi-circle has been removed from one side of it, the area of the BCFG shape is 60 and the area of the CIJF square is 36, compute the length of the AB side of the ABCDE shape. Assume $\pi=3.14$. Round computations to 2 decimal places.
