A farmer wants to fertilize a triangular field with sides of length 300 yd , 220 yd , and 180 yd . Fertilizer costs $ 180 per acre 1 acre = 4840 yd 2 . Furthermore, the time required to fertilizer 1 acre is approximately 2.8 hr with combined labor and equipment costs of $ 23.00 per hour. a. To the nearest acre, how big is the field? b. Using the number of acres from part (a), estimate the cost to fertilize the field. Round to the nearest dollar.
