Answer:
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.

<em>More detail</em>
Any finite decimal can be converted to a fraction by considering the place value of the digits.
3.2 = 3×1 + 2×(1/10)
= 3 + 2/10 = (30 +2)/10 = 32/10
Then common factors can be cancelled from numerator and denominator.
32/10 = (2·16)/(2·5) = 16/5
The negative sign can be applied as required.
-3.2 = -(3.2) = -(16/5) = -16/5
