The ratio of perimeter of an equilateral triangle having an altitude equal to the radius of the circle to the

sorry correct answr = 2:3
solution:in first equilateral triangle altitude =r(radius of a circle)so side will be (a)=2/sqrt(3)(u can find the side with help of pithagoras thrm in that triangle).so perimeter(P1) =3*a
now we have to find the perimeter of that equilateral triangle which is inside the circle of radius r.first find the side of this triangle that will be b=sqrt(3)(use cosine rule to find this side)so perimeter(P2)=3*b
now the ratio=P1/P2=3*a/3*b=2:3
