To work out perimeter you always add I need to remember that

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.

It is a polygon consisting of 5 unit squares that are attached to one another along a length.
Pentominoes are 12 shapes made up of 5 squares !If you rotate or move them they do NOT count as a different pentominoe!
Plus the side
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
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.
Technically, you can't. The Koch snowflake is self-similar. So the perimeter is infinity.
times the numbers by each other.
