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:

area of a rhombus formula 1

In this formula, h is the length of the height and s is the length of any side.

area of a rhombus formula 2

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.

What Are the Four Coordinate Plane Quadrants?

There are four coordinate plane quadrants you’ll need to know when plotting points or graphing lines on the coordinate plane. The coordinate plane, also known as the coordinate grid, cartesian coordinate system, or Cartesian plane, is constructed by taking a vertical axis, or the y-axis and setting it against a horizontal axis, or the x-axis. This creates a grid with four quadrants.

The four coordinate plane quadrants don't have names but are simply known as the first quadrant, second quadrant, third quadrant, and fourth quadrant.
