Question

find the area of equilateral tringle whos perimeter is 12 devide by 3

Answer 1

Heya Frnd.....

Perimeter of equilateral ∆ = 12/3 = 4 cm

Now,

$area \: of \: equilateral \: triangle = \frac{ \sqrt{3} }{4} {s}^{2}$

So,

√3 / 4 * 4²

=> √3 * 4

$= > \boxed{4 \sqrt{3} {cm}^{2}}$............ ★ANS★
