Re: Square

If the area is 49, then each side must be 7 since the figure is a square.   The length of side WZ (and XY) is determined by calculating the difference of the X coordinates, in this case s and 3-s. 

s - (3 - s) = 7
s - 3 + s = 7
2s = 10
s =5

Likewise, the lengths of sides XW and YX can be calculated by finding the different of the y coordinates.

t - (5 - t) = 7
t - 5 + t = 7
2t = 12
t = 6
