area of rectangular sheet = 34 × 24 = 816cm^2
area of 64 circular buttons = 64 × πr^2 = 64 × 22/7 × 3.5/2 × 3.5/2 = 616cm^2
area of remaining sheet = area of rectangular sheet - area of 64 buttons = 816 - 616 = 200cm^2
area of 64 circular buttons = 64 × πr^2 = 64 × 22/7 × 3.5/2 × 3.5/2 = 616cm^2
area of remaining sheet = area of rectangular sheet - area of 64 buttons = 816 - 616 = 200cm^2
