Your task:

Enter a digit (ranging from 0 to 9) in the input boxes on the right side. Then enter its perimeter. Can you create a setup where no digit repeats?

GeoGebra

Create another setup that's different from the one you made above. (And don't just switch the length and width values for the one above either). Create a different length and different width!

GeoGebra

Same task again: Create another valid setup different from the two you created above!

GeoGebra

What is the HIGHEST POSSIBLE VALUE you can get for the PERIMETER here? Create a setup where the PERIMETER IS AS HIGH AS YOU CAN POSSIBLY MAKE IT!

GeoGebra

What is the LOWEST POSSIBLE VALUE you can get for the PERIMETER here? Create a setup where the PERIMETER IS AS LOW AS YOU CAN POSSIBLY MAKE IT!
