In a rhombus ABCD, the diagonal intersect each other at O. If `/_ A =60^(@)` and `OA=2` cm, then the side of the rhombus is `"_______________"`

A

4cm

B

`4 sqrt(3)` cm

C

`2 sqrt(3)` cm

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
d
(i) In a triangle if the angles are `30^(@),60^(@),90^(@),` then the corresponding sides are in the ratio of `1: sqrt(3) :2`.
(ii) ABD and BCD are equilateral triangles.
Altitude of `Delta ABD =OA =2 ` cm
(iv) Height of an equilateral triangle of side 'a' units `=(sqrt(3))/(2) a.`
