Answer:
29.70796327 m
Step-by-step explanation:
You need to add all the sides together which would be 6 + 8 + the circumference of the semi circle.
C = 2(pi)r (in this case it is a semi circle so you can remove the 2 and the radius is 5 (half of 10))
C = (pi) x 5
C = 15.70796327
P = + 6 + 8 = 29.70796327
