Question

Each side of equilateral triangle measure 8cm. Find area of triangle

Answer 1

Answer:

$Area \: the \: triangle (A)\\=16\sqrt{3} \: cm^{2}$

Step-by-step explanation:

side of an equilateral triangle (a) = 8 cm

$Area \: the \: triangle (A)\\=\frac{\sqrt{3}}{4} a^{2}\\=\frac{\sqrt{3}}{4} \times 8^{2}\\=\frac{\sqrt{3}}{4} \times 64\\= 16\sqrt{3} \: cm^{2}$

Therefore,

$Area \: the \: triangle (A)\\=16\sqrt{3} \: cm^{2}$
