Formula
det(A) = a₁₁ × a₂₂ − a₁₂ × a₂₁= -2
Note
Simplified model: these are exact results of the stated idealised formulas, assuming perfect shapes and exact inputs. Real measurements carry error, and the ellipse perimeter is a Ramanujan approximation. Verify independently before relying on these figures.
