Show answer & explanation
Correct answer: B. 12 cm12 सेमी
Explanation
Area of an equilateral triangle = (√3/4)a² = 4√3, so a² = 16 and a = 4 cm. Perimeter = 3a = 12 cm.समबाहु त्रिभुज का क्षेत्रफल = (√3/4)a² = 4√3, अतः a² = 16 और a = 4 सेमी। परिमाप = 3a = 12 सेमी।More Mathematics & Numerical Ability questions
