Can I calculate the width if I only know the area and perimeter?

If you have the diagonal and length, the width is found using the formula width = square root of (diagonal squared minus length squared).

What happens if I enter the diagonal and height?

The calculator will apply the formula width = square root of (diagonal squared minus height squared) to determine the width.

Is the calculator able to work backwards?

Yes, the calculator is omni-directional, meaning you can change the width input and see how it affects the other dimensions like area, perimeter, and diagonal length.
