Answer: 423.52 is the answer
Step-by-step explanation:
First you can find the circumference of the two half circles which make a whole by doing 68 x 3.14 which is pie and you get 213.52
Then you find the perimeter of the square but the two sides are off so you just do 105 + 105 which gets you to 210
Then you add those two and get 413.52
