    For some reason you have Mathcad in the position where it interprets 5h as 05h (that is 5, hexadecimal, equals 5 decimal). The same for a, it is 4h=4.

    Because with h=1/2, you can have either:

    a=2 and r=1.25,

    OR

    a=0 and r=1/4.

    Which only plots the circle, as the square has sides of zero, and sits on -1/4,0.

     

    Success!

      Thanks, Luk!

      It was one error from one my student. And I have showed him how we can work with PTC community.

      1 Use units of length in geometry problems.

      2 Use dot here: 3*h, a*(h-1m) etc.
