Question

Find the area of an equilateral triangle with side 4 under root 768 cm

Answer 1

HELLO.....FRIEND!!

THE ANSWER IS HERE,

Area of equilateral triangle,

$= > \: \frac{ \sqrt{3} }{4} {a}^{2}$

Here, a is the side of the equilateral triangle.


$= > \: a = 4 \sqrt{768} cm$

$= > \: \frac{ \sqrt{3} }{4} ( {4 \sqrt{768} })^{2}$

$= > \: 4 \times 768 \times \sqrt{3}$

$= > \: 3072 \sqrt{3} {cm}^{2}$


:-)Hope it helps u.

Answer 2

Hi Friend !!!

================

The area of equilateral triangle is √3a²/4

where a is the side of equilateral triangle = 4√768cm

= √3(4√768)²/4

= √3 (16)(768)/4

= √3 4(768)

= 3,072√3 cm²

Hope it helps u:-)
