Trapezoid Calculator
Calculate trapezoid area, median, and shape from the two bases and height locally in your browser.
Enter the two parallel bases and the perpendicular height from 0 (exclusive) to 1000000000 to see the area ((a + b) / 2 x h), median ((a + b) / 2), and shape. The calculation runs locally in your browser; your values are not uploaded or stored.

Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What does the trapezoid calculator show?
Enter the two parallel bases and the perpendicular height from 0 (exclusive) to 1000000000. The calculator returns the area ((base A + base B) / 2 times height), the median ((base A + base B) / 2), and the shape (parallelogram when both bases are equal, otherwise trapezoid). For example, base A 10, base B 6, and height 4 give median 8, area 32, and trapezoid shape.
Which formulas does the trapezoid calculator use?
It uses median = (a + b) / 2 and area = median x h, where a and b are the two parallel bases and h is the perpendicular height between them. The shape is parallelogram when both bases are equal and trapezoid otherwise.
Which inputs are accepted?
Enter a base A, a base B, and a height greater than zero through 1000000000. Decimal values are accepted. Zero, negative numbers, non-numeric text, and values above the limit show a clear error instead of a result.
Do my numbers stay private?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter.
