In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
Rectangles do not have congruent lines. A square can always be called a rectangle. But a rectangle can't always be a square.

A rectangle, possibly a square. Can you see why a parallelogram must be a rectangle if any one of its angles is right?
A rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height.
