Question

2.

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.

Answer 1

The answer in here is 20ft and here is how you can get to this answer:
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
