The perimeter of equilateral triangle is 3∗(4163)3 *(^4{\sqrt{16\over3}}) units. Determine the area of the triangle.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 1 unit2.

Perimeter = 3 × (4163 \sqrt{\frac{16}{3}})

Perimeter = 3  × (4163 \sqrt{\frac{16}{3}}) = 12163 \sqrt{\frac{16}{3}} = 12 × 163{\frac{16}{\sqrt3}} = 163 \sqrt{3}

Side = Perimeter​/3 = (163 \sqrt{3})/3

Area = 3 \sqrt{3}/4 a2 = 3 \sqrt{3}/4 ((163 \sqrt{3})/3)2 = (643 \sqrt{3})/3 unit2
