Given the coordinates (7,−3) , (7,−8) , (11,−4) , and (11,−9) , what is the length of the vertical sides of the quadrilateral, in cm?

Question

___cm

Answer 1

The vertical sides of the quadrilateral are the ones with the same x-coordinate:

1. Vertical side with x=7: |-3 - (-8)| = 5 cm
2. Vertical side with x=11: |-4 - (-9)| = 5 cm

Therefore, the length of the vertical sides of the quadrilateral is 5 cm.
