Answer 2

length of one side of the equilateral triangle is 2√3 cm

so,

let a = 2√3 cm

formula for the area of an equilateral triangle is [(√3)/4]×a²

$\frac{ \sqrt{3} }{4} \times {a}^{2} \\the \: \: value \: \: of \: \: \sqrt{3} \: \: is \: \: 1.732 \\ so \\ \frac{1.732}{4} \times ({2 \sqrt{3}) }^{2} \\ = \frac{1732}{4 \times 1000} \times 4 \times 3 \\ = \frac{1732}{4000} \times 12 \\ = \frac{433}{1000} \times 12 \\ = 0.433 \times 12 \\ = 5.196$

so, the area is 5.196 cm²

Hope this helps you.
