A trapezoid is a four-sided shape (quadrilateral) such that one pair of opposite sides are parallel. The figure is popularly known as trapezoid in most parts of the world, but referred to as trapezium in certain countries such as the UK. Since that area is above the curve, but inside the trapezoid, it’ll get included in the trapezoidal rule estimate, even though it shouldn’t be because it’s not part of the area under the curve. Having the form of a trapezoid; trapezoidal; as, the trapezoid ligament which connects the coracoid process and the clavicle. It is also sometimes called trapezium (UK).
