Find the perimeter, in cm, of the composite figure. This image shows a rectangle and a semicircle. Use 3.14 for the value of pi.

perimeter=28.85 cm

Step-by-step explanation:

Hello, I can help you with this

in this case, in this case it is posible divide the area into 2 more known shapes, a rectangle and a semicircle

let's remember

the area of a rectangle is given by

the area of a semicircle is given by

so, the total area is

Step one

Let

base=5 cm

heigth=8 cm

diameter of the circle=5 cm

Step 2

put the values into the equation

so, the total area is 49.81215 square centimeters

to find the perimeter you must add the sides of the rectangle

it is

perimeter of the rectangle =8+8+5=21 cm

now, the perimeter of the semicircle is =pi* radius

Perimeter=(3.14*diameter)/2

Perimeter=(3.14*5)/2

Perimeter=7.85

so, the total perimeter is =21 cm+7.85

total perimeter=28.85

Have a good day.
