Question

5. if l is the length of a side of a regular
pentagon, then write the formula for
finding its perimeter (p).
(with solution)​

Answer 1

Answer:

A regular pentagon has a perimeter of 125. Find the length of one side of the pentagon.

Possible Answers:

35

25

15

20

75

Correct answer:

25

Explanation:

By definition a regular pentagon must have five equivalent sides and five equivalent interior angles. Since this problem provides the measurement for the total perimeter of the pentagon, work backwards using the formula:

p=5(s), where s= the length of one side of the pentagon.

125=5(s)

s=1255=25
