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.
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)
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
Rectangles Perimeter Is 2L + 2W. 2(7) + 2(4) = Perimeter 14 + 8 = Perimeter Perimeter = 22
What is the perimeter of a square
To work out perimeter you always add I need to remember that
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).
It is pi r 2

Technically, you can't. The Koch snowflake is self-similar. So the perimeter is infinity.
times the numbers by each other.
ask your maths teacher
By adding the three sides.
It is different for each shape. A perimeter is the distance around an object and the area is the square units it takes up.
Area: Find some of the lengths, then cut the L in half and work it out from there. Perimeter: Add all the lengths together.
Add up the sides.
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
