Answer
View full question & answer→Area of an equilateral triangle having each side a cm is given by:$\text{A}=\frac{\sqrt{3}}{4}\text{a}^2$
Area of the given equilateral triangle having each equal side equal to 4cm is given by:$\text{a} = 4\text{cm}$
$\text{A}=\frac{\sqrt{3}}{4}(4)^2$
$\text{A}=\frac{\sqrt{3}}{4}\times16$
$\text{A}=4\sqrt{3}\text{cm}^2$
