Let
x -----> the length of the pasture
y -----> the width of the pasture
we know that
The area of the pasture (rectangle) is equal to
we have
substitute and solve for y
X^2 - 5x + 4
-2x^2 + 10x -8
The surface of the water is 0 feet. So 10 feet down means it is 0 - 10, or -10 feet as its final position.
