Answer 1

50.137

Explanation:

You can split the triangle into two triangles both with base 3 and height 12

The area of the two triangles is

`2 * (1/2) * B * H\\B*H = 3* 12 = 36`

The area of a circle is
`\pi r^2`

so the area of the semi circle with r(adius) 3 is

`\pi r^2/2\\9\pi/2`

`9\pi/2 + 36 = 50.137`
