Answer:

Option 3. (2π + 40) mm².

Step-by-step explanation:

Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.

Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²

                     = (4 + 8)/2 × 4 + 4² + (1/2)×π×4

                     = 24 + 16 + 2π = (2π + 40) mm²

Therefore option 3. (2π + 40) mm².
