A parallelogram or a rectangle would fit the given description
A polygon (four sided shape) that has 2 parallel sides with different lengths, and 2 sides with the same length but sort of slanting in. * * * * * No. What is described is an isosceles trapezium. In general, the slanting sides need not be the same length.
There is no such thing a a trapizium. A trapezium is a quadrilateral: that is a plane figure that is bounded by four straight sides. Two of these sides are parallel but of different lengths. (If they were of the same length then the shape would become a parallelogram.)
A shape with four sides has four vertices and a shape with three sides has three vertices, so a shape with four sides has more vertices than a shape with three sides.
A four-sided planar shape (any one) made up of line segments is called a quadrilateral. Any quadrilateral will have the sum of its interior angles equal to 360 degrees. This shape maybe a trapezium, but not necessarily. A trapezium is a quadrilateral with no parallel sides, but it is possible to construct one with a couple of sides that are of equal length.

Add together the lengths of its four sides.
There are no specific names for such a shape.
A rectangle has four sides with two equal lengths.
It is a rhombus
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
A rectangle is generally defined as a quadrilateral with four right angles. No rectangle can have four different side lengths by that definition. Finding the area of such a shape is therefore impossible.
This is a special case of a quadrilateral called a rectangle.
Add together the lengths of the four sides; or add the lengths of the two different sides and then double it.
A shape that has four sides but does not have all sides the same length is called a trapezoid (or trapezium in some countries). In this shape, at least one pair of opposite sides is parallel, while the other sides can be of different lengths. Another example would be a quadrilateral, which can have varying side lengths and angles.
A shape that has four sides but does not have all sides the same is a rectangle. In a rectangle, opposite sides are equal in length, but the adjacent sides can be of different lengths. This distinguishes it from a square, which has all four sides equal. Other examples include trapezoids and irregular quadrilaterals.
Add up the lengths of the sides.
A shape that has four sides and one pair of parallel sides is called a trapezoid (or trapezium in some countries). In a trapezoid, the parallel sides are referred to as the bases, while the other two sides can be of different lengths. This geometric figure is a type of quadrilateral, which means it has four sides in total.
A polygon (four sided shape) that has 2 parallel sides with different lengths, and 2 sides with the same length but sort of slanting in. * * * * * No. What is described is an isosceles trapezium. In general, the slanting sides need not be the same length.
