Need help with solving these problems please help!!

1. Suppose a farmer wishes to construct an enclosure consisting of identital rectangular areas as shownbelow. If the farmer only has 2400 ft of fence find the maximal area they can enclose and the dimensionsof the enclosures that maximize the area.2. A ball is thrown upwards in the air and at time t the ball is at height h(t) = -4t2 + 15t + 2. Use calculusto find the time when the ball achieves the greatest height.3. Suppose a farmer wishes to construct an enclosure consisting of two identital rectangular areas up againsta river (on top) as shown below. Assume the farmer doesn't need to put fencing along the river. If thefarmer only has a 600 me field to construct the enclosure on, find the minimum amount of fence that thefarmer needs to use and the dimensions for the enclosure that maximize it.MAR19....Paw x 1 9F220 F3988F5- F6F7IIF8F9F10%&5689ERT>UO
