Given, Permiter  = 60 degrees

            Side        =  60/3

                            = 20                                   

We know that area  = root s (s-a)(s-b)(s-c)

                                 = root 30 * (30-20)(30-20)(30-20)

                                = root 30 * 10 * 10 *10

                               = root 30000 cm^2
 
                              = 100 root 3 cm^2.



Hope this helps!
