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?

Answer 1

The length of the vertical sides can be found by finding the difference in the y-coordinates of each pair of points.

Vertical side 1: (7,−3) and (7,−8)
Length = |-8 - (-3)| = |-5| = 5 cm

Vertical side 2: (11,−4) and (11,−9)
Length = |-9 - (-4)| = |-5| = 5 cm

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