a) 8V3 cm?
b) 16 V3 cm?
c) 3V8cm?
d) 3V16 cm?​

Answer 1

Answer: (b) 16√3 cm

Step-by-step explanation:

Each side of equilateral triangle, a = 8 cm.

$Area\ of\ equilateral\ triangle=\frac{\sqrt{3}}{4} a^{2} \\\\=>\frac{\sqrt{3}}{4} 8^{2}\\\\=>\frac{\sqrt{3}}{4} *64\\\\=>\sqrt{3} *16\\=>16\sqrt{3}\ cm$
