A rectangle has four sides with two equal lengths.
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.
It is a rhombus

There are no specific names for such a shape.

A rhombus is a shape having two acute angles and four equal sides.
It's the sum of the various individual lengths of the four sides.
A square is defined as a quadrilateral with four equal sides and four right angles. Each of its sides is of equal length, ensuring that the shape is both symmetrical and balanced. The four vertices are the points where the sides meet, forming the corners of the square. This unique combination of equal lengths and right angles gives the square its distinctive properties.
A "parallelogram" technically is a shape where opposite sides are equal and any shape with four sides is a "quadrilateral". Every square has four sides of equal length, so a square is both a parallelogram and a quadrilateral. A rhombus(or diamond shape) can have four sides of equal length and can be a parallelogram as well, so either are possibilities.
That shape is a square. A square is a special kind of rhombus, and a rhombus is aspecial kind of parallelogram. So the shape described in the question is a square,a rhombus, and a parallelogram.ALSO . . . any polygon with more than four sides can have four equal sidesand four right angles.
A rectangle.
