Question
Part 1: Suppose Sally want to put a fence around a rectangular field, where the width (w) is two times the
length (1).
Give an expression for the perimeter of the field in terms of its length (1). perimeter =
Is the perimeter of the field function of its length? O yes
no
Explain with one sentence why or why not.
Part 2: Is the area of the field a function of its length? O yes Ono
Explain with one sentence why or why not.
Part 3: Suppose the field has a length of 8,000 feet. Sally buys fencing to enclose it, but has bought 4 feet
too much. Rather than throwing away the extra fencing, Sally enclose a slightly larger field by enlarging
each side of the field by the same amount, so the fencing encloses the field and a border:
What is the largest animal that could be at point X and be entirely within the border region, touching
neither the fence nor the field?
an ant
a cat
an elephant
a mouse
a cow
Part 4: Give the average rate of change of the perimeter, if the length increases from 8,000 feet to
9,000 feet:
