Question

If the area of an equilateral triangle is 9 root3 cm2 then the length of the each side of triangle is a) 6 b) 2 root3 c) 4 root3 d) 3 root2 *

Your answer


​

Answer 1

area of an equilateral triangle = root 3/4×side square.

so 9 root 3 = root 3/4×side square

so we get side = 6 cm.

Answer 2

this is one of the easiest questions .

Step-by-step explanation:

AREA OF EQUILATERAL TRAINGLE =$\sqrt{3}$/4 SIDE SQUARE

ATQ

----->  9$\sqrt{3}$=ROOT 3 / 4 SIDE SQUARE

-----> 9  ROOT 3 * 4 / ROOT 3

AFTER CANCELLING ROOT 3

U GET  

36=SIDE SQUARE

6 IS THE ANSWER

EACH SIDE IS 6 CM
