ABCD is a rectangle and there are four equilateral triangles . Area of DeltaASD equals to area of DeltaBQCand area of DeltaDRC equals to area of DeltaAPB. The perimeter of the rectangle is 12 cm. Also the sum of the areas of the four triangles is10 sqrt(3) cm^(2) then the total area of the figures thus formed :
