Rajat cuts out two equilateral triangular pieces of cardboard, each of area 300 sq. cm, and then placed them upon a table, one on top of the other such that the triangles completely coincide with each other. Now, if he rotated one of the two triangles by 180∘ about a vertical axis passing through its centroid, find the area that is common to both the triangles. |
