Question

find an area of an equilateral triangle with side 2 under root 3cm is?​

Answer 1

Answer:

6√3 sq.cm

Step-by-step explanation:

area of equilateral triangle = √3/2 side square

√3/2(2√3) square

√3/2× 12

6√3 sq.cm

Answer 2

$\huge{\red{\bigstar{\mathfrak{solution}}}}$

Given :

Length of side of equilateral triangle = 2√3 cm

We know that :

Area of equilateral triangle = √3/4 (a^2)

Here, a = 2√3

$\frac{ \sqrt{3} }{4} {a}^{2}$

$\frac{ \sqrt{3} }{4} ( {2 \sqrt{3})}^{2}$

$\frac{ \sqrt{3} }{4} (4 \times 3)$

$3 \sqrt{3} \: sq \: cm$

Therefore, area of triangle is 2√3 sq.cm
