Want to change the area unit? Simply click on the unit name, and a drop-down list will appear. Trapezium (UK) / trapezoid (US): at least one pair of opposite sides are parallel. The basic ones are: Irregular quadrilateral (UK) / trapezium (US): no sides are parallel.Thats the case in which our parallelogram area calculator is particularly useful. Regular polygon area formula: A = n × a² × cot(π/n) / 4 Determine the perimeter of an isosceles trapezoid with bases of 10 and 15 inches and non-parallel sides of 20 inches each. There are many types of convex quadrilaterals.Quadrilateral area formula: A = 1/2 × e × f × sin(angle).Octagon area formula: A = 2 × (1 + √2) × a².Hexagon area formula: A = 3/2 × √3 × a².Trapezoid area formula: A = (a + b) × h / 2.Circle sector area formula: A = r² × angle / 2.Base a Given Perimeter Base a Given Area Base b Given Perimeter Base b Given Area. Isosceles Trapezoid Formula Area Isosceles Trapezoid. A = a² × sin(β) × sin(γ) / (2 × sin(β + γ)) Calculate base of an isosceles trapezoid step-by-step.

174) is trapezoid in which the base angles are equal and therefore the left and right side lengths are also equal. (5) An isosceles trapezoid (called an isosceles trapezium by the British Bronshtein and Semendyayev 1997, p. For the sake of clarity, we'll list the equations only - their images, explanations and derivations may be found in the separate paragraphs below (and also in tools dedicated to each specific shape).Īre you ready? Here are the most important and useful area formulas for sixteen geometric shapes: (3) An isosceles trapezoid has perimeter pa+b+2c (4) and diagonal lengths pqsqrt(ab+c2). Well, of course, it depends on the shape! Below you'll find formulas for all sixteen shapes featured in our area calculator. The median of an isosceles trapezoid is the line segment formed when we join the midpoint of one leg to the midpoint of the other leg of an isosceles trapezoid.
