Answer:

Step-by-step explanation:

Given that ;

Perimeter of equilateral triangle = 12 cm

∴ Each side =

Each side = 4

Now, we know that ;

Area of equilateral Δ = √3 / 4 a²

                                  = √3 / 4 * 4²

                                  = √3 * 4

                                  = 4√3

Hence, area of equilateral triangle is 4√3 cm².
