Quickly calculate the area and perimeter of any trapezoid with our free online Trapezoid Calculator. Input the base lengths, height, and side lengths to get instant results, making complex geometry problems simple and accurate.

Formula:

Area (A): A = ½(b1 + b2)h
Perimeter (P): P = b1 + b2 + s1 + s2

Where:

  • A = Area of the trapezoid
  • P = Perimeter of the trapezoid
  • b1 = Length of the first parallel base
  • b2 = Length of the second parallel base
  • h = Perpendicular height
  • s1 = Length of the first non-parallel side
  • s2 = Length of the second non-parallel side
