Question

Height of an equilateral triangle measures 9under root 3 find its area

Answer 1

height of equilateral triangle =
$9 \sqrt{3}$
so, area of equilateral triangle =
$\frac{ \sqrt{3} }{4} {a}^{2}$
so, area =
$\frac{ \sqrt{3} }{4} \times 9 \sqrt{3} \times 9 \sqrt{3}$
area = 104.5 approximately.
