How do i write an expression for the perimeter?

To calculate the perimeter, by definition, you must add up all the sides. The details, of course, vary from case to case. For example, if you have an arbitrary triangle, the expression would be something like side1 + side2 + side3 (or whatever the sides are called). In some cases you can simplify the resulting expression; in an isosceles triangle, you have two equal sides, so you get an expression similar to a + a + b = 2a + b. In a rectangle, opposite sides are equal, so you get perimeter = a + b + a + b = 2a + 2b or 2 (a + b).

What does write an expression for the perimeter mean?

Basically, the perimeter of a shape is the total legnth of all it's sides, therefore to write an expression for it, you need to get the legnths of the sides (even if there is a letter (eg: n)), then put them into an expression. For instance: A polygon has 2 sides that are 15cm long, 1 side that is 22cm long, 4 sides that are n long and 3 sides that are a long. To write the expression for the perimeter of this polygon as basically as possible, you would write: 15cm + 15cm + 22cm + n + n + n + n + a + a + a Now you need to simplify it: 52cm + 4n + 3a If you were asked this question, you would write 52cm + 4n + 3a as your answer. That is an expression for the perimeter of that particular polygon. If you apply the same theory to any question like the one you asked about, you would get it right.
