Textbook Question
Chapter 7.3, Problem 53ES
Lake Tahoe One way to measure the area of an irregular figure, such as a lake, is to divide the area into trapezoids that have the same height. Then measure the length of each base, calculate the area of each trapezoid, and add the areas. The following figure gives approximate dimensions for Lake Tahoe, which straddles the California and Nevada borders. Approximate the area of Lake Tahoe using the given trapezoids. Round to the nearest tenth of a square mile.
