Question

What is the area of an equilateral triangle wwith side 2 cm .​

Answer 1

Heyaa,

$Area \: of \: Equilateral \: Triangle \: \\ = > \frac{ \sqrt{3} }{4} {a}^{2} \\ = > \frac{ \sqrt{3} }{4} \times {2}^{2} \\ = > \frac{ \sqrt{3} }{ {2}^{2} } \times {2}^{2} \\ \: \: \: = > \sqrt{3} \: or \: 1.73$

Hope it Helps !!

Answer 2

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

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

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

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

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

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