A person wants to purchase both parcels of land shown in the figure to the right and make a check on their combined area. There is no equation for the river frontage, so the person uses the average of the left sum of rectangles covering the area. The 1,000-foot baseline is divided into 10 equal parts. At the end of each subinterval, a measurement is made from he baseline to the river, and the results are tabulated. Let x be the distance from the left end of the baseline and let h(x) be the distance from the baseline to the river at x. Answer River parts (a) through (c). Parcel I h(x) Parcel 2 550 ft 1,000 ft X 100 200 300 400 500 600 700 800 900 1000 o O h (x) 182 236 242 290 324 389 453 504 550 (a) Use Lip to estimate the combined area of both parcels. The combined area of both parcels is f2 d then click Check
