I own a rectangular piece of property for which I want to construct a fence around the entire perimeter of the property. In order to install the fence, I first have a survey of the property boundary performed.
The surveyors produce a survey of the property boundary on a coordinate grid, where each unit of length is equivalent to 25 feet. The coordinates
of the vertices of my property correspond with the points (-2, 7). (10, 31). (-10, 21) and (-22,-3) on the survey.
Which of the following best estimates the length, in feet, that will be required for my fence?

50 feet
100 feet
1250 feet
2500 feet
