How do you find the area of an irregular polygon?

Area of Irregular Polygons

  1. Coordinates. The first step is to turn each vertex (corner) into a coordinate, like on a graph:
  2. Area Under One Line Segment. Now, for each line segment, work out the area down to the x-axis.
  3. Average the two heights, then multiply by the width.

How do you calculate irregular area?

How to use irregular area calculator?

  1. Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).
  2. 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.
  3. Step 3: Press calculate button.
  4. Our Formula: Area = b × h.

How do you find the area of a 4 sided figure?

Use the following equation: Area = side × side or A = s. Example: If one side of a square has a length of 4 feet, (t = 4), then the area of this square is simply t2, or 4 x 4 = 16 square feet….Parallelograms include:

  1. Squares: Four sides, all the same length.
  2. Rectangles: Four sides; opposite sides have same lengths.

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

The area of any irregular quadrilateral can be calculated by dividing it into triangles. Example: Find the area of a quadrilateral ABCD whose sides are 9 m, 40 m, 28 m and 15 m respectively and the angle between the first two sides is a right angle. The area of the quadrilateral ABCD =(180+126)=306 square meters.

How do you find the area of a 8 sided shape?

Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .

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.

How do you calculate the area of an irregular polygon?

Take any point (inside or outside the polygon,it does not matter,but it’s easier if you do not choose one of the vertices of the polygon).

  • Draw line segments from this point to every vertex of the polygon,giving us a set of triangles.
  • Determine an order on the vertices by going either clockwise or counter-clockwise around the polygon.
  • How do you find angles of irregular polygon?
