Let width of the rectangular plot be x meters
then total of widths = 2x
and the length would be (550 - 2x) meters.
so the area = x(550 - 2x) = 550x - 2x^2
to find the maximum are find the derivative and equate to zero:-
f'(x) = 550 - 4x = 0
x = 550/4 = 137.5 meters = width
length = 550 - 2(137.5) = 275
Maximum area is when width = 137.5m and length = 275m
Factor the equation:

set each part of the factorized equation to zero and solve for x the results are your zeros:
x+3 = 0
x = -3x-8 = 0
x = 8

Answer:
Equations can have many solutions. The equation of a straight
line, for example, defines all points on the line. Even a simple
equation such as x+y=5 can have a variety of solutions (x=1 when
y=4, x=2 when y=3 and so on)
