Answer:
Option (1)
Step-by-step explanation:
Coordinates of the vertices are A(-2, 1), B(2, 7), C(8, 3) and D(4, -3)
Since ABCD is a square,
Perimeter of a square = 4 × (length of a side)
= 4 × (AB)
Formula to calculate the distance between two points and
is,
d =
Therefore, distance between two points A(-2, 1) and B(2, 7) will be,
AB =
AB =
AB =
AB =
Now area of square ABCD = 4 ×
= unit
Therefore, option (1) will be the answer.
