Area of a semi circle = pi * radius^2 / 2
3.14 * 5^2 / 2
3.14 * 25 / 2
78.5 / 2
39.5
Area of a rectangle = length * width
16 * 10

Formula for coordinates of midpoint,
x= (x1+x2)/2
y=(y1+y2)/2,
where (x1,y1), (x2,y2) coordinates of the end-points.
-1=(x1-8)/2
-2=x1-8
x1=-2+8
x1=6
1=(y1+4)/2
2=y1+4
y1=2-4
y1= - 2
