Answer 1

You mean equilateral triangle? You can either use trig ratios or Heron's Formula.

Answer 2

ya can you solve this question and a2 means a square

Answer 3

??????????? can anyone here who can solve this ques...........

Answer 4

\[\sqrt{3}\div4timesa \] and a ka square hai

Answer 5

for a 30:60:90 triangle the side ratios are 1:sqrt3 : 2
so height of triangle is (sqrt3/2)a

Area = 1/2 base*height = a/2 * (sqrt3/2)a = (sqrt3/4)a^2
