Polygons in coordinate plane practice:

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

1 answer

To find the length of the vertical sides of the quadrilateral, we need to calculate the difference in the y-coordinates of the given points.

Vertical side 1:
(7,-3) and (7,-8)
Difference in y-coordinates = -8 - (-3) = -5 cm

Vertical side 2:
(11,-4) and (11,-9)
Difference in y-coordinates = -9 - (-4) = -5 cm

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