The area of equilateral triangle = √3a²/4

= √3×8×8/4

= √3×16

= 16√3

= 27.71 m²

Hope it helps u:-)

Answer 2

HELLO......FRIEND!!

THE ANSWER IS HERE,

Area of equilateral triangle is

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

Here a=8m.

$= > \: \frac{ \sqrt{3} }{4} \times {8}^{2}$

$= > \: \frac{ \sqrt{3} }{4} \times 64$

=> 27.71sq.m

:-)Hope it helps u.
