Two sides of a triangular plot of land measure 510 ft and 237 ft and the angle between them is 78.1 ° a. If the land is $ 5500 per acre, what is the cost for this plot? Round to the nearest dollar and use the fact that 1 acre is 4840 yd 2 . b. If materials for a chain-link fence cost $ 4.20 per linear foot, what is the cost to completely enclose the property? Round to the nearest dollar.
