This holds true for all regular polygons. The probably most commonly used formula including the cross-sectional area is Navier’s formula, which calculates the stress in any point of a cross-section due to bending and axial forces. Area of Parallelogram OR Area of Irregular Shapes () Square Footage Square Feet SqFt Sq Ft sq ft ft. Free Rectangle Area & Perimeter Calculator - calculate area & perimeter of a rectangle step by step. We know that the formula to calculate the area of a rectangle is, Area of rectangle Length × Width. The result is valid for both a horizontal and a vertical axis through the centroid, and therefore is also valid for an axis with arbitrary direction that passes through the origin. Area (A) a (b) Perimeter (distance around the outside of the rectangle) a + a + b + b or 2 a + 2 b and is noted as (P) Diagonal is d ² a ² + b ² which is the Pythagorean Theorem (see our Pythagorean Theorem calculator ). triangle base height Triangle Area × b × h Square Area a Rectangle Area w × h Parallelogram Area b × h Trapezoid (US) Trapezium (UK) Area (.
