No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)
The two are not directly related. You can change the amplitude without changing the wavelength, and vice versa.The two are not directly related.

No, you cannot change the bifocal prescription on glasses without changing the lens. The lens is what is prescribed by your eye doctor. The frame, however, can be changed.

When you (or an object) travel without changing speed, then you have constant velocity (speed). This means there is no change in speed (acceleration) when you (or an object) is traveling.
