Can anyone do this?

12x9 tablecloth has 2x4 triangles cut from diag opp corners leaving 10 top left and bottom right and 5 perpendicular sides, then slants to connect.

With a single cut we are to make a square.

Clue is the area of the odd shape - 100 (12x9-4x2) so 10x10 - but how to do the cut?

5 perpendicular sides? should be 6 if that's 2 triangles

ljdksa - The shape has indeed 6 sides - a sort of square cum rhomboid - the horizontal ones 12-2=10 long and the vertical 9-4=5 high, and the angled (4^2+2^2)^0.5 long
Yes I can visualise the shape- it's an irregular hexagon.
Are you allowed to fold the cloth before you make the single cut?

Please solve accordingly within minutes to stop me having a sleepless night tryind to do it in my head!
