To find the lengths of the vertical sides of the quadrilateral given the coordinates (7,−3), (7,−8), (11,−4), and (11,−9), we can first identify the points that lie on the same vertical lines.
-
The points (7,−3) and (7,−8) lie on the same vertical line (x = 7).
- The distance between these two points is calculated as follows:
- The distance between these two points is calculated as follows:
-
The points (11,−4) and (11,−9) lie on another vertical line (x = 11).
- The distance between these two points is:
- The distance between these two points is:
Thus, the lengths of the vertical sides of the quadrilateral are both 5 cm.
