Yes, you can draw a square with a perimeter of 20 units because all sides would be equal to 5 which would give you 5*4 = 20 units.
Since a sector is a fraction of a full circle, the ratio of a sector's area A to the circle is equal to the ratio of the __central angle__.
The proportion can be written as A/ πr² = ∅/ 2π.
Multiply both sides by πr² and simplify to get ∅/2 * r²
