The area of the smallest equilateral triangle with one vertex on each of the sides of the right triangle with side lengths and <
Gre4nikov [31]
Set up the given triangle on x-y coordinates with right angle at (0,0). So the two vertices are at (5,0) and (0,2sqrt{x} n]{3})

let (a,0) and (0,b) be two vertices of the<span> equilateral triangle. So the third vertex must be at </span>(\frac{a+\sqrt{3}b}{2} ,  \frac{b+\sqrt{3}a}{2} )

for a pt (x,y) on line sx+ty=1, the minimum of \sqrt{x^{2} + {y^{2} }
equals to \frac{1}{ \sqrt{ s^{2} +  t^{2} } }

smallest value happens at \frac{10 \sqrt{3} }{67}

so area is \frac{75\sqrt{3}}{67}

hence m=75, n=67, p=3
m+n+p = 75+67+3 = 145
