Yes, it is. Being congruent means they share the same angles and sides. They both have 7 as the width, and 3 as the height. All of the angles are right angles, because of the square markings on each one. They have the same angles and sides.
The definition of congruence is if <em>two figures or objects have the same shape or size, regardless of how they are placed.</em>
As all the lengths of the sides are all equal (as shown above, where the bases are all 7, and the height are all 3), and that all the angles are equal (all 90°), we can conclude that, yes, the two figures are congruent.
