Can anyone explain how the firt 3 options are right?

min area : equilateral triangle = 27.71
max area : circle = 45.84
So any that fall between these constraints should be valid right?

It doesn’t say the polygon has to be regular

even if it isnt a regular, still the smallest is an equilateral triangle ryt?

What’s stopping the area of an irregular polygon from being in the vicinity of 0?
