Irregular Quadrilateral Area
Area = Triangle 1 (Heron's) + Triangle 2 (Heron's)
Step-by-Step Calculation Example
For a plot with Side A=24m, Side B=20m, Side C=30m, Side D=25m, and Diagonal=35m: Triangle 1 (24, 20, 35) Area = 239.36 m², Triangle 2 (30, 25, 35) Area = 374.17 m². Total Area = 239.36 + 374.17 = 613.53 Square Meters.
Frequently Asked Questions (FAQs)
Why do we need a diagonal to calculate a 4-side irregular plot?
Four side lengths alone cannot uniquely define the shape or area of a quadrilateral. A diagonal splits the plot into two stable triangles, which can then be solved exactly.
What is the formula used in this irregular calculator?
We use Heron's Formula twice. First to solve the triangle formed by Sides A, B, and the Diagonal, and second to solve the triangle formed by Sides C, D, and the Diagonal. The total area is the sum of both.
Can I use any diagonal for this calculator?
Yes, but you must enter the exact diagonal that connects the corner between Side A/B and Side C/D.
