Question

find the area of an eqlateral triangle whose each side is 6​

Answer 1

Step-by-step explanation:

Area of equilateral triangle with side 'a' =root3/4a³

Here a=6cm

⇒ Area =root3/4×6²

=>Area =root3/4×36

⇒ Area =9root3

Answer 2

Answer:

$18 \sqrt{3}$

Step by step explanation:

Area of equilateral triangle is

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

A=6

$\sqrt{ \frac{3}{4} } \times 6 {}^{2}$

$\frac{ \sqrt{3} }{2} \times 6 \times 6$

$\sqrt{3} \times 3 \times 6$

$there \: fore \: 18 \sqrt{3}$
