In a A B C , if A a = B b = C c and the side a=2 , then area of the triangle is

Options

  1. A1 sq unit
  2. B2 sq units
  3. C3 2 sq units
  4. D3 sq units

Correct answer

D. 3 sq units

Step-by-step solution

We have, A a = B b = C c aligned & & A k A & = B k B = C k C & & A & = B= C & & A & =B=C=60^ aligned A B C is an equilateral triangle. aligned Area of triangle & = 3 4 a^2 & = 3 4 2^2= 3 sq units aligned
