1) all sides of a square are equal
2) square II's side length = (x-coordinate of III's lower left corner) - (x-coordinate of I's lower right corner)
2) side of square I = 3
-- points on a vertical line (y-axis here) have the same x-coordinates, but different y-coordinates; for length, use the unequal coordinates
-- Length = absolute value of difference between \(y_2\) and \(y_1 = (3 - 0) = 3\)
3) Square I's lower right vertex/corner is at (3,0); it must be 3 away from origin on the x-axis
4) Lower left corner of square III is at (7,0)
-- upper and lower left corners have the same x-coordinate
-- upper left corner of III is (7,8)
-- so its lower left corner is at (7,0)
5) Square II, between lower right corner of I and lower left corner of III on the x-axis, has side length (7 - 3) = 4
Area of square II = \(s^2 = 4^2 = 16\)

Given information:
1) All squares
2) area
3) Coordinates
How I went about it:
1) Area of a square S^2
2) Of the given coordinates, you are given y = 3 for square one, however since all sides are equal, that means the end of square 1 is x = 3
3) Given that x = 7 for square 3
a) so 7-3 equals one side of square 2
b) all sides are equal,
c) so S^2 = 4^2 = 16
