About the Quadrilateral Area from Diagonals Calculator
For any quadrilateral, the area can be found from its two diagonals and the angle between them — this works for kites, rhombi and general quadrilaterals alike. Each diagonal has its own unit selector, and the area result does too, so you can mix units freely.
Formula: Area = ½ × d₁ × d₂ × sin(θ)
