I think that 10 is 20% of 50
Notice that the two semicircles have a radius of 10/2=5 and that their area is simply the area of a complete circle with a radius of 5. In the center you have a rectangle that is 10 by 8. So the total area is:
A=pr^2+xy
A=25p+80 m^2
A≈158.53 which is:
A≈158.5 m^2 (to the nearest tenth of a m^2)
