Answer:
Step-by-step explanation:
The perimeter of a plane shape is the total distance around the shape.
The lower part of the given shape is a semicircle.
The formula for determining the perimeter of a circle is expressed as
Perimeter = 2πr
Where
π is a constant whose value is 3.14
r represents the radius of the circle.
Since it is a semicircle, the perimeter would be
1/2 × 2πr = πr
Radius = 9 inches
Perimeter of semicircle = 3.14 × 9 = 28.26 inches
The perimeter of the shape would be
5 + 12 + 5 + 28.26 = 50.26 inches
