A child makes a poster on a chart paper drawing a square `A B C D` of side 14 cm. She draws four circles with centre `A ,\ B ,\ C` and `D` in which she suggests different ways to save energy. The circles are drawn in such a way that each circle touches externally two of the three remaining circles. In the shaded region she write a message Save Energy. Find the perimeter and area of the shaded region.
