A rectangle is a 4-sided polygon that always has two sets of parallel sides (it also has sides at right angles, but we can ignore that for now).

A trapezoid is a 4-sided polygon with at least one set of parallel sides (it may have one or two sets of parallel sets).

From this it is apparent that the set of trapezoids includes all rectangles. Hope this helps.
