Q11 of 24 Page 296

AD is the median and G is the centriod of an equilateral triangle. If the length of side 3√3 m, then let us write the length of AG.


Given: length of side = a = 3√3 m


As we know,


Centroid is equidistant from the corners of an equilateral triangle.


Hence, AG is actually the radius of circumcircle to be inscribed around triangle.


As we know, in an equilateral triangle,


Circumradius of an equilateral triangle (r) =


⇒


⇒ r = 3


Then, length of AG = 3m
