What is the perimeter of (-6, 2), (3,2), (-6,-7) (3,-7)

1 answer:

7 0

Hello! So just by looking at the points, I already know that it’s gonna be a square. This is because when we look at the coordinates, The difference if -6 And 3 is 9 And the difference between 2 and -7 is 9. With that being said, each side is 9 inches apart. There are 4 sides. Multiply the length of the sides by 4. 9 * 4 = 36. The perimeter of the square is 36 units.
