Write an equation and solve it to find the answer.



Answer :

Final answer:

To find the length of one side of a regular pentagon, divide the perimeter by 5. In this case, each side of the Pentagon is 0.32km long.


Explanation:

To find the length of one side of a regular pentagon given its perimeter, you can use the formula: Perimeter = 5 x length of one side. Given that the perimeter is about 1.6km, you can set up the equation as: 1.6 = 5 x length of one side. To solve for the length of one side, divide 1.6 by 5, giving you a side length of 0.32km for each side of the Pentagon.
