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?
The vertical sides of the quadrilateral are 5 cm long each.
To find the length of the vertical sides, we calculate the difference in the y-values of the coordinates.
For the first pair of coordinates (7, -3) and (7, -8):
Vertical side length = |-8 - (-3)| = 5 cm
For the second pair of coordinates (11, -4) and (11, -9):
Vertical side length = |-9 - (-4)| = 5 cm
Therefore, the length of the vertical sides of the quadrilateral is 5 cm each.
