The largest area that can be enclosed is 100 ft long (parallel to the river) and 50 ft wide (distance out from the river). It is 5000 ft^2.
_____
You can let x represent the length of the plot (parallel to the river). Then the area is
.. A = x(200 -x)/2
The is the equation for a parabola with x-intercepts at 200 and 0. The vertex is on the line of symmetry, halfway between those x-intercepts, at x=100. For x=100, the area is
.. A = 100*(200 -100)/2 = 100*50 = 5000 . . . . . ft^2

We have been given that a sprinkler is designed to rotate 360∘ clockwise, and then 360∘ counterclockwise to water a circular region with a radius of 11 feet. The sprinkler is located in the middle of the circular region. The sprinkler begins malfunctioning and is only able to rotate 225∘ in each direction.
We are asked to find the area of the sector to nearest square foot.
We will use area of sector formula to solve our given problem.
For our given problem
and
.
Therefore, the sprinkler can water approximately 238 square feet.
