Yes, it is possible to find the area of this hexagon.
Work Step by Step
The diagonal of a regular hexagon is two times the side. As the diagonal of this hexagon is 12 cm long, its side must therefore measure 6 cm in length. There are multiple methods that can be used to find the area of a regular hexagon when the side-length is known, such as multiplying one-half the side length times the apothem.
