Answer:
Step-by-step explanation:
do this in two parts.  one, the rectangle,  two, the circle 
the rectangle , you only have 3 sides to the rectangle. 
2 * 25 = 50
1* 30 = 30
total perimeter of the rectangle = 80 cm
the circle, find the total of the circle, then since there is only half and circle,  multiply that by  1/2 or divide by 2, same thing.
perimeter of a circle is the circumference
circumference of a circle is  2 r   or   diameter
r   or   diameter ,  same thing
   ,  same thing
30 = 94.24777961 cm ( the whole circle )
 = 94.24777961 cm ( the whole circle ) 
1/2*94.24777961 =47.1238898 cm
add the two parts 
   80 + 47.1238898 = 127.1238898 cm
127.12  cm  ( rounded to two decimal places )
