The Trapezium Area Calculator helps you calculate the area of a trapezium (or trapezoid) quickly and accurately.
It uses the standard formula: Area=12(a+b)×h\text{Area} = \frac{1}{2} (a + b) \times hArea=21​(a+b)×h

where aaa and bbb are the lengths of the two parallel sides (bases) and hhh is the height.
Simply enter the two base lengths and height, click Calculate, and the tool instantly shows the area in square units.
Perfect for geometry students, architects, and quick mathematical checks.
