Trying to find the area of a rhombus can be simple. Here, we’ll look at the two formulas for the area that don’t use trigonometry so you can find your answer without too many headaches.

You can use one of these two formulas to find the area of a rhombus: In this formula, h is the length of the height and s is the length of any side. Here, p and q are the lengths of your two diagonals.

Before we show you how to use these formulas, let's explain what a rhombus is.
