hey here is your answer

pls mark it as brainliest

pls refer my reference diagram uploaded above

so here we go

Step-by-step explanation:

so let the required equilateral triangle be triangle abc

so we know that area of equilateral triangle =root 3/4 ×side square

so 39=root 3/4 side square

ie side square =156/root 3

so multiply rhs through by root 3 we get 156×root 3/3

ie side square=52 root 3

so take square roots on both side we get

$\sqrt{52 \sqrt{3} }$
