jenny is building a rectangular garden around a tree in her yard. the southwest corner of the garden will be 2 feet south and 3 feet west of the tree. the northeast corner of the garden is 1 foot north and 4 feet east of the tree. what will be the perimeter of jenny’s garden?

10 ft.
20 ft.
21 ft.
25 ft.

The answer in here is 20ft and here is how you can get to this
If we place the tree at the origin then we can say that
the bottom-left tree is at (-3,-2) 
the top-right tree is at (4,1) 
so the base of the rectangle is 7 
the height is 3 
Taking into account all the details then 
perimeter = 2(7) + 2(3) = 20
Hope this is good enough for you
