<image>If the ABCDE shape is a rectangle where an equilateral triangle has been removed from one side of it, the perimeter of the ABCDE shape is 90, the perimeter of the BFGC rectangle is 56, the BFHI shape is a combination of a rectangle and a semi-circle and the area of the BFHI shape is 84, compute the length of the AB side of the ABCDE shape. Assume $\pi=3.14$. Round computations to 2 decimal places.
