refer to the following: A cell phone provider is expanding its coverage and needs to place four cell phone towers to provide complete coverage of a 100-square-mile area formed by a 10 mile by 10 mile square. This area can be represented by a region on the Cartesian coordinate system; see gure.The placement of the four towers is very important in that the cell phone provider needs to provide coverage of the entire 100-square-mile area. The cell phone towers being installed can process signals from cell phones within a 3.5-mile radius.Engineering. One plan under consideration is to place the four towers in locations that correspond to the points (3, 3), (3, 7), (7, 3), and (7, 7) on the graph. a. Write an equation that describes the perimeter of the cell phone coverage for each of the four towers. b. Draw the coverage provided by each of these towers. Will this placement of towers provide the needed coverage?
