Answer:
P=38
Step-by-step explanation:
At this case I would use the circumference formula for the rounded part.
The formula of the circumference is C=2πr.
So... We know that the radius is 5 which is half of the diameter. So... C=2π5 which is C=10π or C=31.4 which we divide by 4 because on the image is 1/4th of a circle and C/4 which C=7.85 so the P of the whole figure is P=10+10+5+5+7.85 which is P=37.85 which will be P=38.
Answer: P=38
