Answer:
The given theorem proves that the door is not a rectangle right now since, the door came out of shape, it can be proved by the Pythagorean theorem. If the length is set to a certain shape, and the width is set to a certain shape, and drawn to diagonals. If solved by the Pythagorean Theorem, if the length of two diagonals are similar then and only then the door would be a rectangle.
Hope this helps!
I am going to assume that you are looking for the speed of the object. So, knowing that the formula for speed is distance divided by time, we have the expression: 45.5/13. This would simplify to be 3.5 meters per second, or m/s. m/s also happens to be the "Scientific unit for speed!" Just a fun fact! If this answer was not clear, please feel free to ask! Happy home-working!
