Understanding Trapezoid Area

The Formula

The area of a trapezoid is calculated using the formula: A = ½(a + b)h where 'a' and 'b' are the lengths of the parallel sides (bases) and 'h' is the height (perpendicular distance between the bases).

Key Points to Remember

  • The height must be measured perpendicular to the parallel bases
  • All measurements must be in the same units
  • The result will be in square units

Common Applications

Trapezoid area calculations are commonly used in: Architecture for roof designs Civil engineering for road grading Landscape design for irregular plots Manufacturing for material estimation
