Area of Irregular Quadrilateral is calculated by knowing 4 sides and a angle or diagonal of it. This calculator useful for students, Engineers and anyone interested in calculating area of any real life four side object. We can also use it as irregular rectangle area calculator.
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. As illustrated in the figure, a four-sided plot will have two triangular plots (a-d-e and b-c-e).
You will need some additional conditions, like those above. Thus, based on many requests, we've created a model calculator that calculates quadrilateral areas by four sides - for an endless number of quadrilaterals. You can find it at Area of an irregular quadrangle with the given sides.

The Four-Sided Field Size Acre calculator computes the area of a field with four straight sides given the length of the four sides and the length of a diagonal between opposing corners. INSTRUCTIONS: Choose units and enter the following: (A) Length of side a (B) Length of side b (C) Length of side c (D) Length of side d (Dg) Length of the diagonal (See Diagram) Acres in a Field (A): The ...
How do I find the acreage? Frequently Asked Question. 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.
A sector of a circle is essentially a proportion of the circle that is enclosed by two radii and an arc. Given a radius and an angle, the area of a sector can be calculated by multiplying the area of the entire circle by a ratio of the known angle to 360° or 2π radians, as shown in the following equation: area =. θ. 360.
Jan 18, 2024 · A = 0.5 · e · f · sin (α) where: e, f — The lengths of the two diagonals of the quadrilateral; and. α — The angle between the two diagonals. There are two unique angles between the two diagonals, α and (π-α). Since sin (π-α) = sin (α), the quadrilateral area formula yields the same result for both angles. 3.
