Question 529957: What are the perimeter and area of the figure shown (it is a semicircle with two right angels attached to the line of the diameter or radius of the semicircle) if r=30mm, and h (the height attaching the two right triangles as well as attached to the semicircle)= 20mm. *So what I think the question is asking for is the area and perimeter of the whole figure which would be the semicircle and the attached 2 right triangles* Please help... Thank you :)

If I'm visualizing this correctly,
the area 2 ea right triangles plus half a circle:
%2830%2A20%29+%2B+%28.5%2Api%2A30%5E2%29
:
the perimeter, the two hypotenuses plus half the circumference of a circle
2%2Asqrt%2820%5E2+%2B+30%5E2%29+%2B+%28pi%2A30%29
