R=14 cm
total area= πr²
=22/7*196=616 cm²
r2= 3.5 cm
area of the small circles= 2*πr²=2*12.25*22/7=77 cm²
length of rectangle=3
breadth=1
area =lb=3 cm²

area of the small circles+area of rectangle=77+3=80 cm²

remaining area=616-80=536 cm²

Total area of sheet = πr²
                            =22/7*14*14
                            =616 cm²
area of 2 circles = 2*πr²
                        =2*22/7*3.5*3.5
                        =77 cm²
area of rectangle = 3*1
                          =3 cm ²
area of remaining sheet = area of total sheet - [area of 2 circles+area of rect.]
                                 = 616-77+3
                              =536cm²
