Answer 1

See the picture in the attached figure

we know that

[perimeter of the flower garden]=[7+10+10]+[pi*7/2]----> 27+10.99---> 37.99 ft

the answer is
37.99 ft 

Answer 2

Answer:

well, just the fencing is 38 ft, but the full question and answers (just had the question, got all three right) is

What is the perimeter around the three sides of the rectangular section of the garden?  27 ft.

What is the approximate distance around half of the circle? (Use pi = 22/7)

11 ft.

What is the total amount of fencing Helen needs? 38 ft.
