Step-by-step explanation:

The positions of Ankur, Syed and David are represented as A, B and C respectively.As they are sitting at equal distances, the triangle is equilateralAD ⊥ BC is drawn. AD is the median of ΔABC and it passes through the centre O.O is the centroid of the ΔABC. OA is the radius of the triangle.

= 2/3 ADLet the side of a triangle a metres then BD = a/2 m.

AB2 =AD2

AB2 =AD2⇒ AD2 = AB2

⇒ AD2 = a2 -(a/2)2

⇒ AD2 = a2 -(a/2)2⇒ AD2 = 3a2/4

⇒ AD2 = a2 -(a/2)2⇒ AD2 = 3a2/4⇒ AD = √3a/2

⇒ AD2 = a2 -(a/2)2⇒ AD2 = 3a2/4⇒ AD = √3a/2OA = 2/3 AD

⇒ AD2 = a2 -(a/2)2⇒ AD2 = 3a2/4⇒ AD = √3a/2OA = 2/3 AD20 m = 2/3 × √3a/2

⇒ AD2 = a2 -(a/2)2⇒ AD2 = 3a2/4⇒ AD = √3a/2OA = 2/3 AD20 m = 2/3 × √3a/2a = 20√3 m
