Calculating Land Area of Irregular Four Sided Land

Quadrilateral of different shapes such as parallelograms, trapezoids, rhombuses are example of irregular shaped land. Given here is a short tutorial that helps you learn how to calculate the land area of irregular four-sided land.

Learn how to calculate the acreage of a property which is irregular in shape.

How To Calculate Land Area of Irregular Four Sided Land Manually?
Step 1: Split the property into the maximum possible number of regular four-sided parcels such as squares or rectangles. When you split your property, you may result in a number or squares, rectangles and even triangles too. Triangles are seen along the sides of the property.

Step 2: Calculate the area of squares, rectangles and triangles in square feet/yards/meters using the below formulae.

Area of a Square, A = side x side
Area of a rectangle, A = length x width
Area of a triangle, A = (base x height)/2, where height is the height from the base.

Step 3: Sum up the area of all the squares, rectangles and triangles, which gives you the total area of your property in square feet/yards/meters.

Step 4: Convert the total land area of your property (i.e, irregular four-sided land) into acres by dividing the total area in square feet/yards/meters by the relavant conversion units given below.

1 acre = 43560 square feet.
1 acre = 4840 square yards.
1 acre = 4046.8564 square meters.

How To Calculate Land Area of Irregular Four Sided Land using Online Calculators?

Step 1: Determine the shape of the property, whether it is a parallelogram, trapezoid, rhombus, etc.

Step 2: Mark the corners of the property in alphabetical order such as A, B, C and D in clockwise.

Step 3: Measure the distances between the corners such as A-B, B-C, C-D and D-A. Use a surveyors wheel if the property is very large in area. Make sure you measure all the measurements in the same units, which are any of these three feet, yards, meters.

Step 4: Measure the distances between the diagonals of the property such as A-C and B-D in the same unit of measurement used for measuring the sides.

Step 5: Now use any of the online calculator relavant to the shape of your property parcel (parallelogram, trapezoid or rhombus) and input your measurements which give you the total area of the property in square feet/yards/meters as per your input unit.

Step 6:
Convert the total land area in square feet/yards/meters into acres by dividing the total area by the below relavant conversion rates.

1 acre = 43560 square feet.
1 acre = 4840 square yards.
1 acre = 4046.8564 square meters.

NOTE: It is better to calculate the acreage using both the above methods and compare the results for accuracy.
