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 rectang es 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 the 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. Use L1U to estimate the combined area of both parcels, and calculate an error bound for this estimate. How many subdivisions of the baseline would be required so that the error incurred in using Ln would not exceed 5,000 square feet? x 0 100 200 300 400 500 600 700 800 9001,000 h(x) 0 188 237 245 261 290 323 386 444 481 500 The combined area of both parcels is 1 g. The error bound for the estimate is l: ft2. The number of subdivisions required so that the error incurred in using Ln would not exceed 5,000 square feet is n 2 |:.
