Area = Width (w) × Length (l) | Perimeter = 2(w + l)
Dikdörtgen: w × l | Kare: a² | Yamuk: ((a+b)h)/2 | Üçgen: (bh)/2 | Heron: √(s(s-a)(s-b)(s-c)) | Daire: πr² | Dilim: πr²(θ/360) | Düzgün Çokgen: (n·s²)/(4·tan(π/n))Surface area is the two-dimensional extent of a shape. Calconova utilizes an exact Decimal.js arithmetic engine to prevent floating point inaccuracies across all unit conversions.

The area of a trapezoid is computed by multiplying the average of its parallel bases (a and b) by its perpendicular height (h). Formula: A = ((a + b) × h) / 2
First find the semi-perimeter s = (a + b + c) / 2. Then apply Heron's formula: A = √(s(s-a)(s-b)(s-c)). Note that the triangle inequality theorem must hold (sum of any two sides must exceed the third).
For an n-sided regular polygon with side length s, area is: A = (n × s²) / (4 × tan(π / n)).
