You can notice that the shape can be divided into two parts: semi circle and rectangle
the total area=area of semi circle +area of rectangle
area of semi circle =
\frac{\pi {r}^{2} }{2}
since the diameter =10 the radius must be 5
area of rectangle is width * height
therefore
area=
\frac{25\pi}{2}  + 20 \times 10 = 239.25

y=3x+1

Exchanging the position or x and y

x=3y+1

x-1=3y
