Radioactive fallout from testing atomic bombs drifted across a region. there were 210 people in the region at the time and 36 of them eventually died of cancer. cancer experts estimate that one would expect only about 33 cancer deaths in a group this size. assume the sample is a typical group of people. a) is the death rate observed in the group unusually high? b) does this prove that exposure to radiation increases the risk of cancer?

Area of the triangle is base x height, divided by 2, so that is (8 x 10= 80 divided by 2, which is 40.
area of the rectangle is base x height, so that is 3x2= 6
so 40-6 is the area of the shaded region.
so 34 meters squared is your answer.

(length x width x height) x 4$
  (16 x 14 x 3) x 4 = cost
  cost = 2688$
