a right triangle,
a pentagon w/ a right angle,
alot of shapes with right angles.
A trapezoid is defined as a four-sided figure (quadrilateral) with at least one pair of parallel sides. The other pair of sides can be either parallel or non-parallel, and they are not necessarily perpendicular. In some cases, a trapezoid may have perpendicular sides, but this is not a requirement for its classification.
A polygon need not have ANY perpendicular or parallel lines. For example, consider an equilateral triangle. It can happen that two sides of a polygon, extended if necessary, meet at a point where they form a 90 degree angle. Those two lines are perpendicular. There may be pairs of lines such that, no matter how far you extend them in either direction, they will never meet. Such lines are parallel. A triangle cannot have parallel lines but it can have perpendicular lines. Any polygon of 4 or more sides can have sides that are perpendicular or parallel (or some of each).
A square and a rectangle will meet the given criteria.
For the perimeter, you just go round the shape, adding the lengths of each side as you go along. There may or may not be simple formulae of the area for a shape with unequal sides. If all you know is the [different] side lengths then only a triangle has a relatively simple formula for its area. If you also know that some of the sides are parallel, then you can find the area of a rectangle. Then, if you also know the perpendicular distance between the parallel sides, you can do a parallelogram. If, in addition you know which sides are parallel, a trapezium. And so on.
A quadrilateral with one pair of parallel sides and no equal sides is called a trapezoid (or trapezium in some regions). In this shape, the parallel sides are referred to as the bases, while the non-parallel sides can be of different lengths. This distinguishes trapezoids from parallelograms, which have two pairs of parallel sides and equal opposite sides.

Nope it has to be a shape to have parallel sides and even then some don't

A trapezium, and some irregular polygons of 5 or more sides.
The shape you are describing is a trapezoid (or trapezium in some regions). Specifically, it is an isosceles trapezoid, where the two non-parallel sides are equal in length while the two parallel sides are of different lengths. This configuration creates a trapezoid with the specified characteristics.
A trapezoid is a shape that has one pair of parallel faces, specifically in the case of a trapezoidal prism. This three-dimensional figure has two trapezoidal bases that are parallel, while its lateral faces are rectangular, creating perpendicular edges between the bases and the lateral faces.
I think rectangles do not have perpendicular sides. there are some perpendicular sides in a rectangle stupid person
A shape with one or more parallel sides is called a trapezoid (or trapezium in some regions). In a trapezoid, at least one pair of opposite sides is parallel. Other shapes, like rectangles and parallelograms, also have parallel sides. These characteristics are key in distinguishing these geometric figures.
A shape with four sides and one set of parallel lines is called a trapezoid (or trapezium in some regions). In this shape, one pair of opposite sides is parallel, while the other pair is not. The trapezoid can have varying angles and side lengths, but this defining characteristic sets it apart from other quadrilaterals.
