Answer 2

Given :

•An equilateral triangle has side =50cm

• Area=?

To Find :

• Area of equilateral triangle =?

Formula :

$\red \bigstar \boxed{ \sf{area \: of \: equilateral \: triangle = \frac{ \sqrt{3} }{4} {(side)}^{2} }}$

Solution :

The side of the equilateral triangle=50cm

$\\ \implies \sf \: area \: of \: an \: equilateral \: triangle = \frac{ \sqrt{3} }{4} {(side)}^{2} \\ \\ \\ \implies \sf \: area \: of \: an \: equilateral \: triangle = \frac{ \sqrt{3} }{4} \times {(25)}^{2} \\ \\ \\ \implies \sf \: area \: of \: an \: equilateral \: triangle = \frac{ \sqrt{3} }{4} \times 25 \times 25 \\ \\ \\ \implies \sf \: area \: of \: an \: equilateral \: triangle = \sqrt{3} \times 25 \times 25 \\ \\ \\ \implies \sf \: area \: of \: an \: equilateral \: triangle = 625 \sqrt{3} {cm}^{2}$

$\red \bigstar \boxed{ \bf{area \: of \: an \: equilateral \: triangle = 625 \sqrt{3} {cm}^{2} }}$
