A cross-section of an airplane wing is shown in the figure. 150 cm Measurements of the thickness of the wing, in centimeters, at 15-centimeter intervals are 6.2, 20.6, 26.9, 29.0, 27.6, 27.3, 23.7, 20.4, 15.6, 8.5, and 3.2. 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.) cm2

The widths (in meters) of a kidney-shaped swimming pool were measured at 4-meter intervals as indicated in the figure. 2.8 2.5 2.4 3.4 2.4 3.6 3.1 Let x = the distance from the left end of the pool. Determine Ax if the midpoint rule with n = 4 will be used to estimate the area (in m2) of the pool. Ax = Use the midpoint rule with n = 4 to estimate the area (in m2) of the pool. m 2 m
