Median of an equilateral triangle is 15$\sqrt{3}$ cm. What is the side of this triangle ?

24 cm 18 cm 30 cm 36 cm

30 cm

Concept Used Length of a median of the equilateral triangle = \(\frac{√3}{2}\) x side Calculations Let the side of the equilateral triangle be a cm. Length of median of the triangle = \(\frac{√3}{2}\) x a = \(\frac{√3}{2}\) x a = 15√3 = a = 30 cm Therefore, side is 30 cm.
