    Ok. That A stands for Area. And that A is in the triangle. So its saying that the area of the triangle is 20. So we need to find the height of the triangle before trying to find the are of the paralellogram.

    Ok..well one way is that you can put the info you have in the area of a triangle formula and solve fore the height..it would look like this.. (4 x H)1/2=20 SOLVE IT! The 4 is for the Base..the 20 is for the area..
