Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 4 : 3√3

Application

Figure for the explanation of question 61

Diagonal of square = 2r cm

Area of square = 1/2 × (2r)2 = 2r2 cm2

Area of the triangle AOB = (√3/4)r2 cm2

Area of hexagon = (6√3/4)r2 = (3√3/2)r2 cm2

Required ratio = 2r2 : (3√3/2)r2

= 4 : 3√3
