A cross-section of an airplane wing is shown. Measurements of the thickness of the wing, in centimeters, at 19-centimeter intervals are 5.9, 20.8, 26.9, 29.0, 27.3, 27.7, 23.3, 20.5, 15.8, 8.7, and 2.9. Use the Midpoint Rule with n = 5 to estimate the area of the wing's cross-section if a = 190. (Assume the thickness of the edges is nonzero.) ____cm2
