I disagree with your answer.
Start by plotting the points on a piece of graph paper, then calculate the length of one side.
A square has the following vertices. Find the area of the square.
(−7, −5), (−4, −2), (−4, −8), (−1, −5)
6√ square units
18√ square units
6 square units **
18 square units

It's not even a square.

its definately not a square ive been trying to figure this out for my daughter will talk to the teacher tomorrow and hopefully beback with an answer/sollution. i think it may be a typo. :)
End points of one side: (-7, -5), (-1, -5).
A = L^2 = (-1+7)^2+(-5+5)^2 = 36 sq. units.
A = L^2 = (-1+7)^2+(-5+5)^2 = 36 sq. units.
The correct answer is the sqrt of 18 :)
