Exercise: Divide the state into ten subintervals as follows: Starting from the top, draw horizontal line segments across the width of the state every 1 cm down the state. Next, measure the widths of each of these line segments in centimeters and label each segment with its width. Next, use Simpson's Method (with n = 10) to estimate the total area of the state of Illinois. (Use the fact that Illinois has a maximum width of 210 miles to determine the scale of the image below.)
