Ответ:
123m squared
Step-by-step explanation:
First let's get the area of the square by doing 10*10 to get 100, now let's find the area of the semicircle. We can pretend it is a full circle and then cut it in half. We do the radius which is 5 times, pi which is 3.14 to get 15.7. We then square that to get 246.49. Since we want a semicircle we cut that in half to get 123.245. We add this to 100 to get 123.245. Since we have to round, the answer is: The area of the figure is about 123 m2.
