Definition

A trapezoid is a quadrilateral with at least one pair of parallel sides.

Main properties

  • The parallel sides are called bases.
  • Measurements must use the same unit before calculating.
  • Draw a quick sketch to identify each value.

Formula

Area = ((B + b) x h)/2.

Example method

Read the problem, mark the known measurements, choose the formula and simplify the result step by step.
