Final answer:
The formula for the perimeter of a regular pentagon is P = 5 × s, which states that the perimeter (P) is equal to five times the length of one side (s) of the pentagon.
Step-by-step explanation:
The student has asked to translate the sentence 'The perimeter of a regular pentagon is 5 times the length of each side' into a formula. In mathematical terms, the perimeter (P) of a regular pentagon can be calculated by multiplying the length of one of its sides (s) by 5, since a pentagon has five sides of equal length. Hence, the formula can be written as:
P = 5 × s
This is analogous to the way the perimeter of a square is calculated by multiplying the length of one of its sides by 4. The units of measurement for the perimeter will be the same as that of the side length, whether in meters, feet, inches, etc.
