Calculate trapezoid area from its two parallel side lengths and perpendicular separation.

Published · R0

Method and scope

A = ½(a + b)h.

Use trapezoid area for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.

Inputs
  • Parallel side 1 — m, cm, ft
  • Parallel side 2 — m, cm, ft
  • Perpendicular height — m, cm, ft
SOURCE AND LIMITS

Assumptions: The entered sides are parallel and height is the perpendicular separation.

Limitations: Incorrect identification of parallel sides or perpendicular height changes the answer.
