Answer:

  100(π+3) ≈ 614 square units

Step-by-step explanation:

Assuming the rectangles are squares, the total area is that of 3 squares and a circle of radius 10.

  circle area = πr² = π·10² = 100π

  area of squares = 3×s² = 3·10² = 300

Then the total area is ...

  300 +100π ≈ 614 . . . square units
