About this calculator
This calculator finds a trapezoid's area from its two parallel sides (bases) and its height — the perpendicular distance between those two bases — using the standard formula of averaging the two base lengths and multiplying by the height.
It is used by students working through geometry problems, and by tradespeople and DIYers measuring real trapezoid-shaped spaces like a sloped garden bed, a countertop with an angled edge, or a piece of land with two parallel boundary lines, where the shape is not a simple rectangle or triangle.
