Problems of cutting a 2D shape (usually a cake) in multiple pieces of equal areas often occur in daily life. Although the approximation by eye is faster, it is not always accurate. In this paper we are presenting multiple methods of cutting various 2D shapes in 2 or even more pieces of equal area. We also present a method for cutting some shapes with holes in them, with the cake as well as the hole in it having some particular shapes.
