What figure depicts a four sided shape where opposite sides are parallel and have different lengths?

A trapezoid is defined as a four-sided shape (quadrilateral) where at least one pair of opposite sides are parallel, but the key aspect of a trapezoid is that the lengths of these sides can differ. This characteristic distinguishes trapezoids from other quadrilaterals like rectangles and squares, where all sides must have specific relationships or equal lengths.

In a trapezoid, the parallel sides are often referred to as the "bases," while the non-parallel sides are referred to as the "legs." The differing lengths of these bases can lead to various types of trapezoids, such as isosceles trapezoids, where the legs are of equal length, or scalene trapezoids, where all sides are of different lengths.

Other shapes listed have properties that conflict with the requirements of a trapezoid. For example, a square has all sides equal and is defined by all angles being right angles, while a rectangle has opposite sides equal with all angles also being right angles. A rhomboid specifically has opposite sides that are equal in length but is not constrained by right angles like a rectangle or square, and it does not allow for differing lengths of opposite sides in the same manner as a trape
