To determine the area of a rectangle, you can ascertain it by multiplying the length of one side by the length of another side, perpendicular to the first:

Here's an alternative explanation for calculating the area of a quadrilateral by splitting it into two triangles and using Heron's formula: When dealing with a four-sided plot, whether regular or irregular, you can partition it into two triangles. The area of each triangle can then be computed using Heron's formula, which accounts for all three side lengths:

- a, b, and c represent the lengths of the triangle's sides, and
- s is the semi-perimeter, calculated as s = (a+b+c)/2

Choose the number of sides (3 to 10) and enter the lengths of each side.

The tool supports polygons with a minimum of 3 sides and a maximum of 10 sides.

For polygons with 3 sides, Heron's Formula is used. For quadrilaterals, Bretschneider's Formula is applied. For polygons with 5 to 10 sides, Shoelace Theorem (Gauss's Area Formula) is used.

Yes, the tool allows you to input side lengths in meters, feet, inches, centimeters, yards, kilometers, and miles. The result is displayed in multiple units, including square meters, feet, yards, centimeters, cents, and acres.

**Note:** Please ensure that the side lengths are valid for the polygon you are trying to calculate.

**Error:** The side lengths provided cannot form a valid polygon. Please check the input values and try again.

**Success:** The area has been calculated successfully!

- 1 yard (yd) ≈ 3 feet (ft)
- 1 foot (ft) ≈ 12 inches (in) ≈ 30.48 centimeters (cm)
