Answer:
scalene obtuse hope that helps
It is a semicircle so you'd use this formula for the area:
πr² / 2
Then substitute 2 into r and solve (2 because it's the radius, 4 is the diameter)
You would use this formula for the perimeter:
(πd / 2) + d
or
πr + 2r
Then substitute 4 into d / 2 into r and solve.
Hope I helped :)
