The correct answer is option 4 i.e  6$\sqrt[]{3cm2}$

Given that

An  equilateral triangle of side 6 cm

now it cutoff from its corner to form a regular hexagon

then the cutoff side will be 2 cm to form a regular hexagon

Formula used 

The area of the regular hexagon = 6 (√3/4) side²

Calculation

The area of the regular hexagon = 6 × (√3/4) × 2² = 6√3 cm²
