Examine the diagram and information to answer the question. Square ABCD has vertices at A(−2,1), B(2,7), C(8,3), and D(4,−3). How many units is the perimeter of square ABCD?

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.
