Considering any one side,

For convenience, I choose BC
BC=BD+DE+EC
We can prove that BD=DE by congruency
Also, BE= 2*radius of circle= 2(1)=2 units
We need to find BD;
So, In triangle O2BD
Using tan30= O2D/BD
get the value of BDand consequently value of BC
Once the value of BC is achieved, you can easily find the area of the triangle by
Area of an equilateral triangle= (3^1/2)(a^2)/4 where a is the side of an equilateral triangle.
