Answer:

  • Add 75 for the blank number

----------------------------

Divide the figure by three parts for easy calculation of its area:

  • Rectangle of 5 by 10 units,
  • Square of 5 units,
  • Quarter-circle of 5 units radius.

Find each area and add up:

  • A = 5*10 + 5*5 + π*5²/4
  • A = 50 + 25 + 25π/4
  • A = 75 + 25π/4

The blank is 75.
