The calculation essentially relies on the fact a trapezoid's area can be equated to that of a rectangle: (base 1 + base 2) / 2 is actually the width of a rectangle with an equivalent area. In order to use our area of a trapezoid calculator, you need

Perimeter of a trapezoid can be calculated using the following equation of area of a trapezoid calculator: P = a + b + c + d Perimeter of a trapezoid can also be calculated using this

Anyway, good job though , It's the best app even without paying money, best math homework helper in the buisness, happily paid for the year, i can understand better with this, i hate algebra with a burning passion, but this app makes my life so much easier.

AMAZING all around calculator and equation solver, and if you have no clue how to do a problem it will show you if you want to know, but I notice that when you can't answer the question you'll write"hmm, but it gives different solutions for that problem.

Any problem you need done it will do, it is very simple and easy to use, and I have not yet encountered anything wrong with it. But it puts a smile on my face when I open this app and finaly start to understand what I am learning.
