Question

2) If the side of an equilateral triangle is 2√3 cm
then find its area, perimeter and height?​

Answer 1

$area = \frac{ \sqrt{3} \times ( {2 \sqrt{3} )}^{2} }{2} = > \frac{ \sqrt{3} \times 4 \times 3 }{2} = > 6 \sqrt{3} \: {cm}^{2}$

$perimeter = 3 \times 2 \sqrt{3} \\ = > 6 \sqrt{3}$

$area = \frac{1}{2} \times h \times 2 \sqrt{3} \\ = > 6 \sqrt{3} = \frac{1}{2} \times h \times 2 \sqrt{3} \\ = > h = \frac{ 6 \sqrt{3} \times 2 }{2 \sqrt{3} } \\ = > h = 6cm$
