If you're stuck on your geometry homework trying to figure out the area of a quadrilateral, you've come to the right place! Remember—the "area" of a shape is just how much 2-dimensional space it takes up. For some quadrilaterals, there's a handy formula you can use to calculate the area.

How to find the area of any quadrilateral

A quadrilateral is a polygon we obtain by joining four vertices, and it has four sides and four angles. Some examples of the quadrilaterals are square, rectangle, rhombus, trapezium, and parallelogram. The area of a polygon refers to the space occupied by the flat shape. It is the combined sum of the area of the regular and irregular triangles within. To evaluate the area of a quadrilateral, we divide it into two basic geometric figures, such as triangles. Then we find the area of the two individual triangles using the formula and add these areas to find the area of the quadrilateral. We can calculate the area of different types of quadrilaterals by using the given formula. For the quadrilateral ABCD, if we use centimeter as the unit of measurement, the unit of measure for the area will be cm 2. To evaluate the area of a parallelogram, draw a perpendicular from one of the vertices to the base. This perpendicular is the height. Thus, the area will be the product of base and height. To find the area of a rhombus, we divide the quadrilateral into two equal isosceles triangles using the two diagonals. Thus the area of the rhombus is:. Using this relationship we can also find the area of a square ABCD. The area of a rectangle using the above formula will yield the product of its two adjacent sides, base and height.

Geometry Intro to Areas. So once again, the area of this one is going to be 2. It might not be exactly halfway through a unit.

The area of the quadrilateral is the region enclosed by the four sides of this polygon. There are two types of quadrilaterals - regular and irregular. On this page, you will learn how to find the area of any type of quadrilateral, be it a square or a trapezium. You will learn the following topics on this page. Definition of area of a quadrilateral. Types of quadrilateral.

If you are wondering how to find the area of any quadrilateral, check out this quadrilateral calculator. We implemented three quadrilateral area formulas so that you can find the area given diagonals and angles between them, bimedians and angles between them, or all sides and two opposite angles. In the default option, you can also find the quadrilateral perimeter. If you are looking for a specific quadrilateral shape - for example, a rhombus or a kite - check our comprehensive list of area calculators below. A quadrilateral is a polygon with four edges and four vertices. Sometimes it is called a quadrangle or a tetragon, by analogy to three-sided triangles and polygons with more sides pentagon, hexagon, heptagon, octagon, etc. Quadrilaterals can be:. Assume that you want to calculate the area of a parcel.

Terms and Conditions. A parallelogram has 2 parallel sides—those are the bases b. And then finally, this is a 3 by 4 rectangle. Multiplication Tables. So let me try to raise this up to see if I can make another triangle where it would be easy to figure out its dimensions. For squares, multiply one side by itself to get the area. But parallelograms don't look like rectangles most of the time, so what's going on? Necessary Necessary. Create an account. Definition of area of a quadrilateral. But what else does bh tell us? What is the difference between quadrilateral and triangle?

Our area of quadrilateral calculator will help you to determine the area of any quadrilateral with different known parameters.

Find the area of the rectangle. The concept is highly useful in the advanced designing of navigation maps scaled to actual distances and areas with precision. Step-by-step guide: Area of a trapezoid. Area of a Quadrilateral. Then divide the quadrilateral into two parts using the diagonal you found, find the area of each triangle using Heron's formula and then add the areas of two triangles which gives the area of the quadrilateral. Area of Quadrilateral Formula Using Sides. If you draw a diagonal line from one corner to the other, you create 2 triangles within the quadrilateral. Which of the following is not a polygon? First, you need to decompose the right trapezoid into a rectangle and a triangle. The sum of all the angles of a quadrilateral is degrees.
