Answer:
Remaining end points are; (-7, 4) and (-7, - 2)
Perimeter = 24
Step-by-step explanation:
We are given one of it's sides as;
located at (-1,4), and (-1,-2)
We can see that the x - value in both points are -1. Thus, the length of this side would be the difference of the y - value. Thus, side length = 4 - (-2) = 6
Since it is a square, the four sides will be the same length.
Now, the horizontal side perpendicular to (-1,4) have it's y value as 4 too.
Thus, the coordinate is (x, 4). Since a side is 6. Then;
(-1) - x = 6
-x = 6 + 1
x = -7
3rd coordinate is (-7, 4)
Now, the horizontal side perpendicular to (-1,-2) will have it's y value as -2 too.
Thus, coordinate is (x, -2)
Since a side is 6. Then;
(-1) - x = 6
-x = 6 + 1
x = -7
4th coordinate = (-7, -2)
Perimeter of a square = 4 × side length
Perimeter = 4 × 6 = 24
