ROOT 6
ROOT 3
ROOT 2​

Answer 1

Given

• SIDE of Equilateral triangle = 2 cm

We Find

• Area of given equilateral triangle

We Know

Area of equilateral triangle is :-

$\boxed {\red{\frac{ \sqrt{3} }{4} \times {Side}^{2} }}$

According to the question

Area of equilateral triangle = ${\frac{ \sqrt{3}}{4} \times {a}^{2}}$

Area of equilateral triangle = ${\frac{ \sqrt{3}}{4} \times {2}^{2}}$

Area of equilateral triangle = ${\frac{ \sqrt{3}}{4} \times {4}}$

Area of equilateral triangle = ${\frac{ \sqrt{3}}{\cancel{4}} \times {\cancel{4} }}$

Area of equilateral triangle = ${ \sqrt{3} }$

Hence Area of equilateral triangle is ${\pink{ \sqrt{3} }}$
