Answer:
see explanation
Step-by-step explanation:
The perimeter is the length of all the sides in the figure.
The arc of the semi- circle is included in this.
length of arc =
πd ← d is the diameter
here d = 8, hence
arc =
π × 8 = 4π ← exact length
Perimeter = 10 + 8 + 10 + 4π ≈ 40.57 in ( nearest hundredth )
Hmmm. 20 or 30 so the teacher will count the rest,if a student guessed, wrong or right
