⠀⠀⠀⠀⠀

Given

⠀⠀⠀⠀⠀

• Side of equilateral triangle = 16cm

⠀⠀⠀⠀⠀

To Find

⠀⠀⠀⠀⠀

• Area of equilateral triangle

⠀⠀⠀⠀⠀

Solution

⠀⠀⠀⠀⠀

$\bf Area \: of \: equilateral △ = \frac{ \sqrt{3} }{4} \times {side}^{2}$

⠀⠀⠀⠀⠀

$\bf \implies \frac{ \sqrt{3} }{4} \times {16}^{2}$

⠀⠀⠀⠀⠀

$\bf \implies \frac{ \sqrt{3} }{ {2}^{2} } \times {2}^{8}$

⠀⠀⠀⠀⠀

$\bf \implies \sqrt{3} \times {2}^{6}$

⠀⠀⠀⠀⠀

$\bf \implies \sqrt{3} \times 64$

⠀⠀⠀⠀⠀

$\bf \implies64 \sqrt{3} {cm}^{2}$
