Calculation Formula

Area = (Base1 + Base2) × Height ÷ 2

Where:
Base1 = Top base of the trapezoid
Base2 = Bottom base of the trapezoid
Height = Height of the trapezoid

How to Use the Trapezoid Calculator

  1. Enter the length of the top base (Base 1) in centimeters (cm).
  2. Enter the length of the bottom base (Base 2) in centimeters (cm).
  3. Enter the height of the trapezoid in centimeters (cm).
  4. Enter the length of the left side (Side 1) in centimeters (cm).
  5. Enter the length of the right side (Side 2) in centimeters (cm).
  6. Click the "Calculate" button to compute the area and perimeter.
  7. Click the "Reset" button to clear all fields and start over.

Understanding the Results

The calculator provides two main results:

  • Area: The area of the trapezoid is calculated using the formula: Area = (Base1 + Base2) × Height ÷ 2. This gives the total area covered by the trapezoid in square centimeters.
  • Perimeter: The perimeter of the trapezoid is the sum of all its sides: Perimeter = Base1 + Base2 + Side1 + Side2. This gives the total length around the trapezoid in centimeters.

Principle Explanations

A trapezoid is a quadrilateral with at least one pair of parallel sides. The parallel sides are called the bases, and the perpendicular distance between them is the height. The formula for calculating the area of a trapezoid assumes that the height is measured perpendicular to the bases.

The perimeter calculation simply adds up all four sides of the trapezoid, regardless of whether they are parallel or not.
