Asked by Emily

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!!

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
