What is the length of the bottom of the triangle. Use it on the formula for the area of the triangle add it with the area of the rectangle which is 49 times 20. The area of a circle is PiR^2 and the radius is 10 since the width is 20. Divide by 2 and you get a semicircle. (15*20)/2+49*20+50Pi Which is 1130 + 50 Pi.

Just break it into pieces and add them together

triangle on left 1/2 b h        1/2 (49-34) (20)

middle rectangle   width x height  (34)(20)

right semicircle  1/2 pi r^2   = 1/2 pi (10)^2
