How do you find the area of a 4 sided irregular shape?

To find the area of such irregular quadrilaterals, follow a three-step strategy:

1. Divide the quadrilateral into two triangles by constructing a diagonal that does not disturb the known interior angle.
2. Calculate the area of each triangle, using formulas.
3. Add the areas of the two triangles.

What is an irregular shape with 4 sides called?

Irregular Quadrilateral
Irregular Quadrilateral: a four-sided shape where no sides are equal in length and no internal angles are the same. All internal angles still add up to 360°, as with all other regular quadrilaterals.

What is the area of irregular shapes?

Therefore, the area of the given irregular shape = Area of all the polygons that form the irregular shape. Method 2: In some cases, the irregular shape is divided into small unit squares or grids. The total number of unit squares falling within the shape determines the total area.

How to calculate the area of an irregular shape?

How to use irregular area calculator? Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other). Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2. (See image above).

How to name an irregular quadrilateral area calculator?

Also name the angle measured or known, as the sides between it is present. For example, Angle between sides B and C is named as BC, Diagonal between corners AB and CD is named as AB-CD. Enter the values of sides in the Calculator as per named A,B,C,D. Choose the Angle or Diagonal Name from drop down menu.

How to calculate the area of a four sided lot?

We often get questions about the area of parcels of land. We’ve created a tool (below) that should help you if your property has four sides you can measure. In addition to the four sides, we’ll need to know either a diagonal or the degrees of one of the angles. Note that this tool assumes the shape is convex, not concave.

Which is an example of an irregular shape?

Bookmark added to your notes. Irregular shapes are polygons with five or more sides of varying lengths. These shapes or figures can be decomposed further into known shapes like triangles, squares, and quadrilaterals to evaluate the area.
