Answer:

The side of the triangle is 12cm.

Step-by-step explanation:

Let the side of the equilateral be a cm

Area of an equilateral triangle = √3/4a²

                                        36√3 = √3/4a²

                            36√3 x 4/√3 = a²

                                       36 x 4 = a²

                                   9 x 4 x 4 = a²

                                √9 x 4 x 4 = a

                                         3 x 4 = a

                                        12cm = a
