Explanation:
the figure is a combination of
1 half-circle with radius 30/2 = 15
1 inner rectangle 13 width, (13+20)= 33 length.
2 right-angled triangles with 20 being one leg, and (30-13)/2 = 17/2 = 8.5 the other leg.
the area of the half-circle is
pi×r²/2 = pi×15²/2 = pi×112.5 = 353.4291735...
the area of the inner rectangle is
13×33 = 429
the area of one triangle (because they are right-angled, their area is leg1 × leg2 / 2)
20 × 8.5 / 2
but we have 2 triangles, and their total area is then
20 × 8.5 = 170
in total the area of the combined figure is the sum of all 3 numbers :
952.4291735...
this should be the cut-off 3rd answer option 952.4.
