Area of the Rhombus is
(1/2) × diagonal AC × diagonal BD.
Based on that, plug in the given values and solve. Hopefully the steps are clear enough (:

I'm not sure if you have learnt rationalising of the denominator. By rationalising the denominator, you can change a fraction whose denominator contains a surd to a rational number.
If you do know how to do that, then do not do step 5. Instead, rationalise the denominator by multiplying with [(3√3)-4]/[(3√3)-4].
If you managed to follow the steps, you would get BD= [6(17+√3)]/11.
