I need help on these 3 calculus questions:



Question 11 (1 point) Suppose a farmer has 2400 feet of fence and wishes to create two rectangular pens of the same dimensions with the two pens sharing one side (i.e. since the pens share one side, there is a total of 7 sides of fence). What is the maximum area of each of the pens? O 120, 000 square feet O 140, 100 square feet 5,760,000 49 square feet O 108, 500 square feet O 240, 000 square feet Question 12 (1 point) Suppose f(x) is a function with the following properties: . f"(-1) =f"(0) = f"(1) = 0, . f"(x) > 0 for all x on(-co, -1) U (1, co), and . f"(x)
