Area of an arch given angle. Step 2: Enter length of horizontal sides into Length 1 and Length 2. The generally accepted manner for finding the area of an irregular polygon is to break it up into triangles and possibly a rectangle, then calculate each and add the totals. Unlike a regular polygon, unless you know the coordinates of the vertices, there is no easy formula for the area of an irregular polygon. Enter the length and width of the side of the rectangle. Area of an Irregular Polygon. Use this calculator to calculate properties of a regular polygon. Perimeter of a Irregular Polygon Calculator . But the trick is to add when they go forwards (positive width), and subtract when they go backwards (negative width). Triangles do NOT need to be right triangles. One way to calculate areas of such plots, is to break them into a number of triangular-shaped plots as in image shown below and then find the area of each triangle using Heron's formula and sum them up. The program can also be used to calculate the area of land lot. Irregular and Regular Polygon Area Calculation by Excel The attached Excel program can calculate the area of a polygon, either in the form of regular polygons such as triangles, equilateral triangles, cubes, rectangles, hexagons, etc., as well as irregular polygons. Enter the number of sides of chosen polygon. And Width of the vertical sides into Width 1 and Width 2. In general, perimeter refers to the distance around the outer side of the polygon. Now add them all up! Note: due to computer rounding errors the last digit is not always correct. Step 3: Press calculate button. Area of Regular and Irregular Polygon shapes. A polygon is the two dimensional object. Area of an arch given height and radius. SketchAndCalc™ is the only area calculator capable of calculating areas of uploaded images. Upload any Image or Search a Map Address. Area of a regular polygon. In this case, the vertices of the polygon are in rows 2:6. In case you have a polygon with more than 10 vertices, divide it into smaller polygons find the area of each polygon and … In our example, it's equal to 5 in. Radius of circle given area. How to use irregular area calculator? This will work for triangles, regular and irregular polygons, convex or concave polygons. This online calculator which calculates area of a polygon given lengths of polygon sides and diagonals which split polygon to nonoverlapping triangles. This free area calculator determines the area of a number of common shapes using both metric units and US customary units of length, including rectangle, triangle, trapezoid, circle, sector, ellipse, and parallelogram. Area of an arch given height and chord. How to use the calculator Enter the number of points n that form the irregular polygon and the coordinates x and y of the vertices and press "calculate area".

Each side could be a different length, and each interior angle could be different. You do not have to enter … (See image above). To do this you need lengths of diagonals: BD and AD, but this is all you need. Unlike a regular polygon, unless you know the coordinates of the vertices, there is no easy formula for the area of an irregular polygon. If you want to know how to find the area of a variety of polygons, just follow these steps. Area of a circle. Put 12 into the number of sides box. As you can see I added the first vertice again at the end. Trace Multiple Irregular Areas of an Image or Map. Calculator Use Polygon Calculator. As shown on picture, to calculate area of the polygon ABCDE, you can sum areas of triangles ABD, BCD and ADE. Unlike regular polygon, irregular polygon does not holds the same length on each sides. Maybe you know the coordinates, or lengths and angles, either way this can give you a good estimate of the Area. It uses the same method as in Area of a polygon but does the arithmetic for you. Area of a circular sector. Calculates side length, inradius (apothem), circumradius, area and perimeter. This Polygon Calculator uses different converter function in order to generate the Output in different units such as Inches, Feet, Meters, Centimeters and Millimeters. Calculating the area of a polygon can be as simple as finding the area of a regular triangle or as complicated as finding the area of an irregular eleven-sided shape. Area of an Irregular Polygon. Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other). Can you draw your polygon?


Angles and Curves. It uses the same method as in Area of a polygon but does the arithmetic for you. The trick to finding the area of an irregular polygon or complex shape is to break the shape up into regular polygons such as triangles and squares first, then find the area of those shapes and add them together to find the total. The vertices coordinates must be input in order: either clockwise or anticlockwise. Metric and Imperial. Area of an ellipse. The area is width×height: 1.94 × 3.495 = 6.7803 . Edit. Area Calculator – Find the Area of 10 Geometric Shapes. Each side could be a different length, and each interior angle could be different. The only Area Calculator you'll need. Enter the length of the sides for each triangle you use; up to 10 of them. The output our calculator provides is independent of the unit of measurement. Add Them All Up. Let's assume that you want to calculate the area of a specific regular polygon, e.g. Our area of polygon calculator displays the area. Area of Polygon by Drawing.
