Step 1: Set up a area of the equilateral triangle formula.

            NOTE: Equilateral triangle all sides are equal.

                     Area of equilateral triangle = \frac{\sqrt{3}}{4} a^2


Step 2: Plug in the side (a) value in the area of the equilateral triangle formula

             EXAMPLE:  Side a = 10 cm

                                 \frac{\sqrt{3}}{4} a^2   =   \frac{\sqrt{3}}{4} (10)^2


Step 3: Do Some calculations for the answer.

                                            =   \frac{\sqrt{3}}{4} (100)   

                                            =   \sqrt{3}* 25

                                            =   25 \sqrt{3}
