Question 10. Fig is not clear but I can tell you that you have to find perimeter of the rectangle first. Then width is also the diameter of the semicircle so you can find circumference. Since there are 2 semicircles directly add the circumference to the perimeter and you will find the distance. I'll follow this question so if you have any doubt you can ask.

Question 11. Circumference=3.5 X 22/7
                                          =2.2m
                            Cost     =   2.2 X 25      
                                        =Rs. 55
