Correct Answer : II. Choice (2)

Explanatory Answer

  1. Area of circle of radius
  2. Area of an equilateral triangle whose sides each have length
  3. Area of a triangle whose sides measure 3, 4 and 5. The given triangle is a right triangle.
    Hence, its area =  = 6 sq units
We need to compare these three numbers.

Area of the circle,  = 6.28 sq units

Area of the equilateral triangle,  = 6.92
Area of the right triangle = 6 sq units.
