perimeter of coordinates, (-2,4) (0,4) (-2,2) (0,-2) (2,0) (2,-2)

Answer 1

1. Draw the coordinates on a grid.
2. Count the horizontal and vertical lengths: 2, 2, 2 and 2
3. Use the distance formula to find the diagonal lengths: 4.47 and 4.47
4. Add up the lengths of all the sides: 16.94

Answer 2

Two of the sides are vertical, and each of these sides has a length of 2.

Two of the sides are horizontal, and each of these sides has a length of 2.

The total of the above lengths is 4×2= 8.

There are 2 more sides. These sides each has a length of 2√5, or a total of 4√5.

The perimeter is 16.94, rounded to 2 decimal places.
