A cross-section of an airplane wing is shown in the figure. 160 cm Measurements of the thickness of the wing, in centimeters, at 16-centimeter intervals are 5.6, 20.6, 26.9, 29.0, 27.7, 27.2, 24.1, 20.1, 16.3, 8.3, and 3.1. Use the midpoint rule with n = 5 to estimate the area (in cm2) of the wing's cross-section. (Assume the thickness of the edges is nonzero.) cm 2
