How to solve this equation in symbolic form so that the resulting solution can be used as a formula in Excel?

Is it possible?

C = constant

with(Units[Standard]);
A := 2*Unit('Pa');
x := 0;
sqrt(A^2);

In this example defining the 'x' variable returns an error message: "Error, (in simplify/sqrt/fraction) invalid input: denom expects its 1st argument, x, to be of type {algebraic, list, set}, but received pascal".

You can use any Unit in 'A' variable.

Using a Cyrillic font in the Combo Box component gives an runtime error when saving workbook file (*.maple file extension).

Hello!

Using a geometry package, I ran into a problem: the area() function returns the wrong value for square elements.

What am I doing wrong?

I have a problem using variables values that were read form Maple library file (*.mla) with units.

For example:

In the first file called "calculations.mw" I calculate a variable with units and save value to "lib1.mla" file

Download calculations.mw

In the second file called "document.mw" I can read the value of a variable, but can't use it in expressions:

Download document.mw

Where I made a mistake?
