To answer this question we will use the following formula to compute the perimeter of a rectangle:
[tex]Perimeter=2(length+width).[/tex]
Substituting length=200 ft and width=85 ft we get:
[tex]Perimeter=2(200ft+85ft).[/tex]
Simplifying the above result we get:
[tex]\begin{gathered} Perimeter=2(285ft) \\ =570ft. \end{gathered}[/tex]
Answer: Last option.
