A parallelogram has sides 8 and 12. The shorter altitude is 6. Find the length of the other altitude.


It says the answer is 9, but I don't know how they got that. Any help is greatly appreciated!!


  • math (geometry) -

    The area is base*height(altitude)

    So if the base is 12 and the height is 6 then the area is 72

    but we can also calculate the area with the other base and the other height.
    Let the other height be h

    then (8)(h) = 72
    h = 9

    Oh, ok, that makes a lot more sense. Thank you very much!
