How to do base x height on a parallelogram. I'm Bon Crowder with MathFour.com and we're going to talk about parallelograms and finding the area and how to do base x height on the parallelogram. So here we have a parallelogram along this bottom is the base and the height is like this. Keep in mind that the height is not over here or on this side, this is not the height. So how we do this is we actually have some numbers. So let's say our base is 8 and our height is 4. Okay, base x height on a parallelogram gives the area so we do base is 8 x height is 4 and our area is 32 square units. And that's how you do base x height on a parallelogram.
