The equilateral triangle with side PQ is referred Tri_R (opposite to vertex R).
The equilateral triangle with side QR is referred Tri_P (opposite to vertex P).
The equilateral triangle with side RP is referred Tri_Q (opposite to vertex Q).

From Pythagoras' theorem in right angled triangle RPQ,
________ (1)

Now, area of an equilateral triangle with side equal to is .
So, area of Tri_P is _____ (2)
So, area of Tri_Q is _____ (3)
So, area of Tri_R is _____ (4)

So, [from (3) and (4)]
or
or [from (1)]
or [from (2)]
