Question

The length of each said of an equilateral triangle of area 18 √3cm2

Answer 1

Answer:

$area = 18 \sqrt{3} \\ \frac{ \sqrt{3} }{4} \times side {}^{2} = 18 \sqrt{3} \\ side {}^{2} = 18 \sqrt{3} \times \frac{4}{ \sqrt{3} } \\ side {}^{2} = 18 \times 4 \\ side = \sqrt{72} \\ side = 6 \sqrt{2}$
