Answer:

4[tex]\sqrt{3\\}[/tex] ≈ 6.93 cm²

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ← s is the side length

here s = 4, thus

A = [tex]\frac{4^2\sqrt{3} }{4}[/tex]

   = [tex]\frac{16\sqrt{3} }{4}[/tex]

   = 4[tex]\sqrt{3\\}[/tex] ≈ 6.93 cm²
