Answer 1

Given that length of the sheet = 34cm.

Given that breadth of the sheet = 24cm.

We know that Area of rectangle = length * breadth

                                                      = 34 * 24

                                                      = 816cm^2.



Given Diameter = 3.5cm.

Then the radius r = d/2

                              = 1.75cm.

We know that Area of circle = pir^2

                                               = 22/7 * (1.75)^2
 
                                               = 9.625.


Then the area of 64 circular buttons = 9.625 * 64

                                                              = 616cm^2.


Therefore the area of the remaining sheet = 816 - 616

                                                                        = 200cm^2.


Hope this helps!
