From a sheet of cardboard in the shape of a square of side 14 cm, a piece in the shape of letter B is cut off. The curved side of the letter consists of two equal semicircles & the breadth of the rectangular piece is 1 cm. Find the area of the remaining part of cardboard.                     (Ans: 143.5 cm 2 )

Ans:    Area of remaining portion = Area of square - Area of 2 semi circles - Area of rectangle

= 14 x 14 - Π x 3.52 - 14 x 1
