It would be 250 in because you see 10x20 is 200 and and 10x10 is 100. But since part of the figure is a triangle you have to dive it by 2 and 100/2=50. 200+50=250
Hope that helps!
Well if he gets one of hes green balls out 12 times the next time he has a chance of 18%
49 x 138 = 6762
37 x 49 =1813
6762 - 1813 = 4949 so your answer is 4949.
