Answer: The answers are given below.
Step-by-step explanation: Given that all the sides of a pentagon are (s-2) units long. This clearly tells us that the pentagon is a regular one with each side equal to (s-2) units.
We are to write the perimeter of the pentagon in four different expressions.
Let 'P' represents the perimeter of the pentagon.
Since it is a regular pentagon, we can write the perimeter in following four expressions.
P = (s-2) + (s-2) + (s-2) + (s-2) + (s-2),
= 5 × (s-2),
= 5s - 10,
= 5s - 5×2.
Thus, these are the four expressions for the perimeter of the pentagon.
