Given :-

Side of an equilateral triangle is a km

To Find :-

Area of equilateral triangle

Solution :-We know that,

$\huge \green { \boxed{ \boxed{ \mathsf{ \mid \ulcorner Area = \frac{\sqrt{3}}{4} \times s^2 \urcorner \mid }}}}$

Where S is the side of an equilateral triangle

____________[Put Values]

$\sf{ area = \frac{ \sqrt{3} }{4} {s}^{2} } \\ \\ \sf{area = \frac{ \sqrt{3} }{4} {a}^{2} }$

Extra Information :-

• In a equilateral triangle triangle all the sides are equal
• In this type of triangles all the angles are also equal i.e. 60°
