Answer 2

$\textrm{Area of an Equilateral Triangle = }\rm{\dfrac{\sqrt{3}}{4} \times Side^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\dfrac{\sqrt{3}}{4} \times (2 cm)^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\dfrac{\sqrt{3}}{4} \times 4 cm^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\sqrt{3}\times 1cm^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\sqrt{3}\times cm^{2}}$

$\to\textrm{Area of an Equilateral Triangle = }\rm{\sqrt{3}cm^{2}}$
