Question

If each side of an equilateral triangle is 8 cm long, then its area is cm².

Answer 1

False
$$\begin{gathered} \mathrm{Area}\mathrm{of}\mathrm{equilateral}\mathrm{triangle}=\frac{\sqrt{3}}{4}\times (\mathrm{Side}{)}^2 \\ =\frac{\sqrt{3}}{4}\times (8{)}^2 \\ =\frac{\sqrt{3}}{4}\times 64 \\ =16\sqrt{3}{\mathrm{cm}}^2 \end{gathered}$$
