It depends what shape the section is, ie what the length and width are. If you can specify this I can work out the perimeter length.
How do you work out perimeter of an oblong?
You simply have to measure all the sides of the oblong and add them together. If the opposite sides of it are equal (making it a rectangle), then you just need to measure the two different sides and add them together, then multiplying the result by 2. perimeter = a + b + c +d or perimeter = 2(a+b)

Work out the perimeter of the semi-cirle when diameter is 15cm?
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
