Median of an equilateral triangle is 15$\sqrt{3}$ cm. What is the side of this triangle ?
Answer & explanation
Correct answer: option 3
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.
