A rectangle is one of the types of quadrilaterals in which all four angles are right angles or equal to 90 degrees. It is four-sided polygon in which the opposite sides are parallel and equal to each other.
For the given situation,
The diagram shows a four sided polygon.
In the polygon, the opposite sides are parallel and are equal.
All the angles of the polygon are right angle that is 90°.
Thus the polygon that satisfies these criteria is rectangle.
Hence we can conclude that the diagram shown is a rectangle.
