It’s surprising, to me, that the address adder and the ALU are so comparable in area. I’m guessing the adder is like 1/3 the size of the ALU even though the ALU has so much more functionality. My guess is the flip flops needed to register the operands and resultant compromise a significant chunk of the area in both and the extra 2/3 area in the ALU is the area of the combinational logic to implement all the extra math functions.
