anything imaginary but a real shape would be a square or rectangle.
16cm.
16cm
Perimeter of rectangle: 5+3+5+3 = 16cm
Any type of polygon can have a perimeter of 16 cm. There is no special name for polygons whose perimeter is 16 cm.

It is impossible to tell because there are infinitely many possible solutions.
3 + 3 + 5 + 5 = 16cm
IF 16cm is EACH side, the answer is four (sides) times 16cm... so that's 64 cm.
16cm
16cm.
The perimeter of this square is 45.25 cm
16cm
Perimeter of rectangle: 5+3+5+3 = 16cm
The perimeter is all the way around the shape so it would be.. 16 + 16 + 2 + 2 = 36. Therefore th perimeter must be 36cm.
80 cm
