Question

The perimeter of an equilateral triangle is 100 m. The area is?​

Answer 1

Step-by-step explanation:

$side = \frac{100}{3} \: m \\ \\ area = \frac{ \sqrt{3} }{4} ( {side)}^{2} \\ \\ = \frac{ \sqrt{3} }{4} \times \frac{100}{3} \times \frac{100}{3} \\ \\ = \frac{2500 \sqrt{3} }{9} \: square \: metres.$
