Step-by-step explanation:

$area \: of \: equilateral \: triangle = \pi \times \frac{ {a}^{2} }{3} \\ = \frac{22}{7} \times \frac{ {(18)}^{2} }{3} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (value \: of \: \pi = \frac{22}{7} ) \\ = \frac{22}{7} \times \frac{324}{3} \\ = \frac{22}{7} \times 108 \\ = \frac{2376}{7} \\ = 339.42$

Therefore the area of equilateral traingle with circumference is 339.42
