Calculated result
Enter measurements and select Calculate.
Trapezoid-specific solving
Area = (a+b)h÷2 and midsegment = (a+b)÷2. Reverse modes solve h = 2A÷(a+b) or b = 2A÷h−a.
Geometry boundary
Entered-leg mode reports perimeter from the supplied side lengths without asserting compatibility or assuming an isosceles trapezoid. Invalid reverse-solved bases are rejected.
