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.

What is an expression for the perimeter of a rectangle that has a length which is three times its width?
call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x
The length of a rectangle is 13.6cm the perimeter of the rectangle is 37.8cm what is the width?
Write an equation for the perimeter, and solve it. Remember that the perimeter is the sum of all four sides.
How do you simplify an expression for the perimeter and area of a rectangle?
Represent the length of the rectangle by L and the width by W. The perimeter = 2L + 2W = 2(L + W). The area = L x W.
How do you write an expression for a perimeter?
Perimeter = Sum(length of each side), where the summation is over all the sides.
How to Write an expression for the perimeter of a rectangle with a sides of 3x and 8y?
The perimeter of a rectangle is the sum of the four sides.
How do you write an expression for the distance around a square?
Perimeter covers the boundary line of any plane figure.

Write an expression for the perimeter of a pentagon?
P = 5s, where s is the length of a side. This applies to a regular pentagon. If the pentagon is irregular then P = (s1 + s2 + s3 + s4 + s5)

How can you explain if you can write a division expression as a decimal?
You can always write a numerical division expression as a decimal.
The expression 4 ∙ √125 3 gives the perimeter of the base of a cube with a volume of 125cubic inches. What is the length, in inches, of the perimeter of its base?
To find the length, in inches, of the perimeter of the base of the cube with a volume of 125 cubic inches, we need to calculate the perimeter of the base using the given expression: 4 ∙ √125. The expression √125 represents the square root of 125, which is equal to 11.18 (rounded to two decimal places). Now, we can calculate the perimeter of the base by multiplying 4 by the square root of 125: Perimeter = 4 ∙ √125 = 4 ∙ 11.18 = 44.72 (rounded to two decimal places) Therefore, the length of the perimeter of the base of the cube is approximately 44.72 inches.
What is a variable expression for the perimeter of the square with side 2x plus 1?
