Answer:
Let the side of an equilateral triangle
= a = 4 cm
Area = A = ( √3/4 ) × a²
A = ( √3/4 ) × 4²
A = ( √3 × 4 × 4 ) / 4
A = 4√3 square cm

Step-by-step explanation:
Area of equilateral =
[tex] \sqrt{3}a ^{2} \div 4 \: \: [/tex]

[tex]4 \sqrt{3} [/tex]
[tex]4 \times 1.732[/tex]
[tex]6.928cm²[/tex]
