Question

Three coins of unit radius are placed in an equilateral triangle as shown in the following figure The area of the equilateral triangle is

  1. 6 plus 4 square root of 3    
  2. 20 plus 8 square root of 3    
  3. 7 plus 4 square root of 3    
  4. 2 plus square root of 3    

The correct answer is: 6 plus 4 square root of 3


    Length of the side equals 2 plus 2 square root of 3 ; A r e a equals fraction numerator square root of 3 over denominator 4 end fraction a to the power of 2 end exponent
