    1. Best Answer

      Let the radius of circle = r, Circumference of circle (perimeter) = 2πr, Area of circle = πr²
      Given that the perimeter and area are equal in magnitude. Therefore
      2πr = πr²
      ⇒ 2 = r
      Therefore, the radius of circle is 2 units.
      Hence, the option (A) is correct.
