The coordinates of three vertices of square ABCD are A(−2 1/2,1 1/2),B(−2 1/2,−3),A(-2 1/2,1 1/2),B(-2 1/2,-3), and C(2,1 1/2)C(2,1 1/2).When point D is placed on this square, what will the perimeter of the square be?Enter your answer in the box.

Answer 1

why repeat everything? So annoying
AB = 4 1/2
so the perimeter is 4 * 4 1/2 = 18

Answer 2

it is called study and do your practice work!!!

Answer 3

it is. but its also a bit complicated and stuff were most likely not gonna use in the future
