Ok so for 1000m= 1km that means since 500 is half of 1000, 1/2 is half of 1
Perimeter of a rectangle:
P = 2(l + w)
Plug in what we know:
P = 2(16 + 7)
Add:
P = 2(23)
Multiply:
P = 46
Now find the perimeter of the semi-circle.
Perimeter of a circle:
P = pi * d
Plug in what we know:
P = 3.14 * 16
Multiply:
P = 50.24
Divide by 2 since it's a semi-circle:
50.24 / 2 = 25.12
Add the two perimeters:
46 + 25.12 = 71.12
